add rascript-cli command line interpreter

[Jamiras]

Allows rascript files to be processed from the command line for people who prefer to use other editors (like VSCode).

It does not provide the same feature set however. There's no way to see what changes are being applied to individual achievements, and only update specific achievements. The tool effectively does an Update Local with everything in the Update column checked. It will abort if there are any errors.

The tool has one required parameter.

rascript-cli 1.13.0
========================
Usage: rascript-cli [-v] [-q] [-i script] [-o outdir] [-a author]

  -v            (optional) enabled verbose messages
  -q            (optional) disable all messages
  -i script     specifies the input file to process
  -o outdir     (optional) specifies the output directory to write to [default: current directory]
                will append RACache\Data to the specified directory if an RACache\Data subdirectoy exists
  -a author     (optional) specifies the author to attribute the achievements to [default: Author]

-i specifies the path to the input file.
-o specifies the path to the output directory. If not provided, the current directory will be used.
-a specifies which author to use in the XXX-User.txt file. If not specified, Author will be used. When uploaded to the server, the logged in user will be attributed to the new achievements.
-q suppresses all output
-v adds additional output

Some examples:

The first run is a successful run. 20 achievements and 1 leaderboard were written to the XXX-User.txt file, and 987 bytes were written to the XXX-Rich.txt file.

The second run illustrates an error, and reflects the same error as would be reported in the UI:
