Add Text replicate, spaces

[ari-becker]

Adds a function which generates Text with the number of spaces specified by the parameter.

I believe that this merits addition to the standard library because, when generating a configuration file with dhall text, it is common for configuration files to have significant whitespace (indentation etc.), and adding this function would make it significantly easier for users to generate precise amounts of whitespace in order to match downstream configuration format requirements.

How about adding a more general function

Text/replicate : Natural -> Text -> Text

instead?

If we prefer to stick with this one, I'd suggest calling it Text/spaces.

[sjakobi]

The implementation could also be slightly simplified by using Prelude.List.replicate.

Yeah, I also think a Text/replicate function would be great and should be easy to implement in terms of List/replicate and Text/concat

[ari-becker]

Cool, I've incorporated both of your feedback. I did decide to keep generateWhitespace (now spaces) as a separate function from replicate as I think that it's a common-enough use-case to merit inclusion as a distinct function.

I'm slightly concerned about API bloat with spaces, but not too much.
