v4.3.0

v4.3.0

Changes:

• Invalid arguments are not allowed anymore, and have explicit error-messages.

Improvements:

• The new draw module (the tiny terminal-drawing API for trimsec, for errors) is now even more stable, since it now adjusts printing based on the terminal's max width.
• The error arrow is now (slightly) more precise, sometimes even attempting to pinpoint to the exact index of an error-causing argument.
• The parser delegate for the trim command now ignores arguments invalid to its context rather than bailing out - this case is covered by the first-stage parser itself.
