This also prevents unwanted `raises: [ValueError]` effects from bubbling
up from correct format strings which makes `fmt` broadly unusable with
`raises`.
The old runtime-based `formatValue` overloads are kept for
backwards-compatibility, should anyone be using runtime format strings.

* Allow use of colons inside fmt
allowing colons inside fmt by replacing the format specifier delimiter lets arbitrary nim code be run within fmt expressions.

* formatting,documentation,backslash escapes
Adding support for evaluating expressions by special-casing parentheses causes this regression: `&"""{ "(hello)" }"""` no longer parses.
In addition, code such as &"""{(if open: '(' else: ')')}""" wouldn't work.
To enable that, as well as the use of, e.g. Table constructors inside curlies, I've added backslash escapes.
This also means that if/for/etc statements, unparenthesized, will work, if the colons are escaped, but i've left that under-documented.
It's not exactly elegant having two types of escape, but I believe it's the least bad option.
