Keep a letter after a digit in the same word in Title, Pascal and Camel case [patch] - #107

…el case [patch] TextInfo.ToTitleCase capitalises a letter that follows a digit, so "1st place" became "1St Place" and "abc123def" became "Abc123Def", while snake_case, kebab-case and MACRO_CASE kept "1st" and "123def" whole. ToPascalCase().ToSnakeCase() therefore disagreed with ToSnakeCase(). ToTitleCase now lowers each letter that directly follows a digit after title-casing, so every converter treats digit-to-letter as part of the same word.

Fixes #78
What changed
This follows the maintainer's decision on the issue: a letter after a digit does not start a new word.
TextInfo.ToTitleCasecapitalised any letter that came straight after a digit. As a result,"1st place"became"1St Place", and Title, Pascal and Camel case disagreed with Snake, Kebab and Macro case.ToTitleCasenow runs a newLowercaseLettersAfterDigitsstep after title-casing, which lowers each letter that directly follows a digit. Everything elseTextInfodoes stays as it was, including its handling of apostrophes, punctuation and the dotted and dotless I.1st place1st Place1stPlace1st_placeabc123defAbc 123defAbc123defabc_123defmd5hashMd 5hashMd5hashmd_5hash3d model3d Model3dModel3d_modelTests
