Switch-case statements can now start at any number

[Nico314159]

Simple change that doesn't affect the optimization. Useful because often ones needs it to start at a value of 0 or -1 instead of at 1.

NOTE: this still keeps the "numbers have to be in sequence without skipping" restriction.

Changed line 167 to say datapack.add_raw_private_function(name, func_contents[min_ - start_at], count) instead of datapack.add_raw_private_function(name, func_contents[min_ - 1], count), which should fix your issue.
