COM_Server command line tool

A simple command line tool to start the API server that interacts
with the serial port in an development environment or a 
production environment.

The server started by the CLI will contain routes for all supported 
versions of the builtin API.

Usage:
    com_server run <baud> <serport>... [--env=<env>] [--host=<host>] [--port=<port>] [--s-int=<s-int>] [--to=<to>] [--cors] [--no-rr] [-v | --verbose] 
    com_server -h | --help
    com_server --version

Options:
    --env=<env>     Development or production environment. Value must be 'dev' or 'prod'. [default: dev].
    --host=<host>   The name of the host server (optional) [default: 0.0.0.0].
    --port=<port>   The port of the host server (optional) [default: 8080].
    --s-int=<s-int>  
                    How long, in seconds, the program should wait between sending to serial port [default: 1].
    --to=<to>       How long, in seconds, the program should wait before exiting when performing time-consuming tasks [default: 1].
    --q-sz=<q-sz>   The maximum size of the receive queue [default: 256].
    --cors          If set, then the program will add cross origin resource sharing.
    --no-rr         If set, then turns off /register and /recall endpoints, same as setting has_register_recall=False
    -v, --verbose   Prints arguments each endpoints receives to stdout. Should not be used in production.

    -h, --help      Show help.
    --version       Show version.

Notes:

1. The CLI now supports adding multiple ports. The program will try the ports in the order they are given and use the first port that works.

> com_server run 115200 /dev/ttyACM0 /dev/ttyUSB0 /dev/ttyUSB1

The program will first try /dev/ttyACM0, then /dev/ttyUSB0, then /dev/ttyUSB1, and it will use the first serial port that works.
