Trim lines when reading mrt note to deal with extra spaces

[PozayLol]

Fix for extra space breaking everything. For example, having a note like:

intstart 
... // Interrupt assignments here
intend

will not work, because of the extra space after intstart. The idea here is to trim every line (instead of just the note, as is done on line 111) to resolve all such issue.

Another solution would be to instead match "intstart" and "intend", but not really sure how efficient that is in LUA / went with easier solution.

Oops just realized auto-formatter hit a bunch of random lines (extra spaces at the end of lines funnily enough), I can remove if it's problematic, only important change is line added line 113
