Bug (?): Newlines after template substitution.

[ryan-roemer]

Really neat to see this slim library! I think I've encountered a bug in the handling of whitespace/newlines after template replacements...

Situation

I have multiline template strings that I'm switching away from chalk to this library of the form:

colorize`
{gray One}

{cyan Two}

Expected behavior: Output preserves newlines, so One\n\nTwo with color chars.

Actual behavior: Output strips newlines and whitespace after template replacement, so OneTwo with color chars.

Failing Unit Tests

I think these unit tests demonstrate the issue:
