Update README

Change spacing

Aesthetic.  Removed space before parentheses, tho:
save 1b.

Use ^D instead of ZZ

One byte control character.
Saves 2b

Don't force removal of O; it should remove on its own

saves 1b

Don't exit on error

saves 3b

Move TM to L; change I/ file names

TM->L saves 3b
changing I/ filenames to include the output extension before the input extension
saves 4 bytes, and it's more flexible: it can output any type of files now.
