v1.2.0

This version brings 2 main changes (and a couple documentation comment changes):

• BREAKING: player_id was renamed to plid everywhere for consistency between UCID and PLID
• LFSText.unicode_to_lfs_bytes() no longer converts / to ^s if it appears as the first character in the string; this allows properly parsing MST packets as commands.
