Move reverse from stdlib_ascii to stdlib_strings

[Pranavchiku]

When I build, it throws me following error, I am not sure why it happens:

This is strange. Which compiler do you use?

GFortran

[awvwgk]

This PR introduces a regression in functionality by removing the support for string_type.

I don't think that this PR is the appropriate solution to the observed issue, but I have no clue what the problem could be. What the original module including reverse appropriately compiled?

[Pranavchiku]

Okay, what will be a way to get the issue fixed?

It seems that there is an issue with dependencies, maybe with cmake?
