Jim Mussared 6f8157d880 tools/mpremote: Add hashing ability and use for recursive copy.

Changes in this commit:
- Adds transport API `fs_hashfile` to compute the hash of a file with given
  algorithm.
- Adds commands `mpremote <...>sum file` to compute and print hashes of
  various algorithms.
- Adds shortcut `mpremote sha256sum file`.
- Uses the hash computation to improve speed of recursive file copy to
  avoid copying a file where the target is identical.

For recursive copy, if possible it will use the board's support (e.g.
built-in hashlib or hashlib from micropython-lib), but will fall back to
downloading the file and using the local implementation.

This work was funded through GitHub Sponsors.

mpremote -- MicroPython remote control

This CLI tool provides an integrated set of utilities to remotely interact with and automate a MicroPython device over a serial connection.

The simplest way to use this tool is:

mpremote

This will automatically connect to a USB serial port and provide an interactive REPL.

The full list of supported commands are:

mpremote connect <device>         -- connect to given device
                                     device may be: list, auto, id:x, port:x
                                     or any valid device name/path
mpremote disconnect               -- disconnect current device
mpremote mount <local-dir>        -- mount local directory on device
mpremote eval <string>            -- evaluate and print the string
mpremote exec <string>            -- execute the string
mpremote run <file>               -- run the given local script
mpremote fs <command> <args...>   -- execute filesystem commands on the device
                                     command may be: cat, ls, cp, rm, mkdir, rmdir, sha256sum
                                     use ":" as a prefix to specify a file on the device
mpremote repl                     -- enter REPL
                                     options:
                                         --capture <file>
                                         --inject-code <string>
                                         --inject-file <file>
mpremote mip install <package...> -- Install packages (from micropython-lib or third-party sources)
                                     options:
                                         --target <path>
                                         --index <url>
                                         --no-mpy
mpremote help                     -- print list of commands and exit

Multiple commands can be specified and they will be run sequentially. Connection and disconnection will be done automatically at the start and end of the execution of the tool, if such commands are not explicitly given. Automatic connection will search for the first available serial device. If no action is specified then the REPL will be entered.

Shortcuts can be defined using the macro system. Built-in shortcuts are:

a0, a1, a2, a3: connect to /dev/ttyACM?
u0, u1, u2, u3: connect to /dev/ttyUSB?
c0, c1, c2, c3: connect to COM?
cat, ls, cp, rm, mkdir, rmdir, df: filesystem commands
reset: reset the device
bootloader: make the device enter its bootloader

Any user configuration, including user-defined shortcuts, can be placed in .config/mpremote/config.py. For example:

# Custom macro commands
commands = {
    "c33": "connect id:334D335C3138",
    "bl": "bootloader",
    "double x=4": {
        "command": "eval x*2",
        "help": "multiply by two"
    }
}

Examples:

mpremote
mpremote a1
mpremote connect /dev/ttyUSB0 repl
mpremote ls
mpremote a1 ls
mpremote exec "import micropython; micropython.mem_info()"
mpremote eval 1/2 eval 3/4
mpremote mount .
mpremote mount . exec "import local_script"
mpremote ls
mpremote cat boot.py
mpremote cp :main.py .
mpremote cp main.py :
mpremote cp -r dir/ :
mpremote sha256sum :main.py
mpremote mip install aioble
mpremote mip install github:org/repo@branch
mpremote mip install gitlab:org/repo@branch
