feat: Support minute second typed strings

[silasb]

Context:

Adding the ability to use minute (') and second (") annotation for typed input when building walls. What I ended up doing is if you don't put a minute or second annotation in you'll default to inches. If you specify just the minute annotation the next digit is considered a second operation and can be unit less.

I also updated the status bar to show the live typed input.

In Imperial mode:

12 -> 12 inches 12' -> 12 feet 12'6 -> 12 feet 6 inches 12'6" -> 12 feet 6 inches 9" -> 9 inches

Doesn't affect metric mode.
