quote progress args

[mapsam]

Arguments using the watchbot-progress.sh command that included spaces in a JSON value were misinterpreted as multiple arguments. Here's an example:

metadata='{"hello":"i have a space"}'
output=$(watchbot-progress set-metadata --parts $parts --metadata "$metadata")

This results in an incomplete JSON being sent to the actual watchbot-progress script, and the following error:

{"hello":"i
                                                          

SyntaxError: Unexpected end of input

Wrapping the $@ in quotes, "$@" resolves the issue by preserving strings with spaces.
