Capitalises first letter in ordinal string (e.g. 1St, 2Nd, 3Rd)

[rubengmurray]

I'm trying to use this package across a range of strings which on occasion include written ordinal numbers e.g. 1st time, 2nd time, 3rd time.

This unfortunately returns 1St Time, 2Nd Time, 3Rd Time.

I'm willing to have anyone challenge otherwise here but I can't really see a use case for this so i'm proposing that strings starting with numbers are excluded.

(Or at least provide an optional parameter for it?)
