Add tuple fix function

[acordonez]

When a tuple such as ModUnitsAdjust is read from the command line, it is split by character and not usable in this format.

For example, the tuple (True, 'multiply', 1e-2) gets parsed as ('(', 'T', 'r', 'u', 'e', ',', ' ', "'", 'm', 'u', 'l', 't', 'i', 'p', 'l', 'y', "'", ',', ' ', '1', 'e', '-', '2', ')').

This function re-formats the tuple so that it will be correctly formatted as (True, 'multiply', 0.01). If the tuple is already in this format, the function does nothing.

Confirmed below both demo returns the same result

Case 1:

t = (True, 'multiply', 1e-2)
fix_tuple(t)

Case 2:

t = "(True, 'multiply', 1e-2)"
fix_tuple(t)

Result:
(True, 'multiply', 0.01)
