[Feature Request] Start with loaded table from passed argument

[brkzlr]

Prerequisites

• I have looked through the Wiki and asked (either in Discord or GitHub discussions) to confirm this feature doesn't already exist
• I have searched existing issues (both open and closed) to ensure this hasn't been requested before

Feature Description

Passing a pct table as an argument to PINCE, like the following:
./PINCE.sh ~/path/to/table.pct
or
sudo -E ./PINCE-x86_64.AppImage ~/path/to/table.pct
should start the GUI and have the table loaded in automatically.

Use Case / Motivation

Will help users who automate PINCE's startup or workflow.

Will be especially helpful once PINCE won't require a terminal session once #177 and #289 are done as you can just double click on a correctly associated pct file to start PINCE.
