Support booleans and numbers as i18n content

[nank1ro]

Describe the bug
slang doesn't support booleans

To Reproduce
Have a json file with something like

{"enabled": true}

Expected behavior
No errors, enabled returns the true value.

Additional context

Unhandled exception:
type 'bool' is not a subtype of type 'Map<String, dynamic>'

additionally if you have {"number": 200} you get back the string "200" instead of the number 200

Thanks for the issue. This is an edge case as almost all i18n solutions (including slang) only handle strings.
I marked it for v5 because it might be breaking - Unfortunately, don't expect a release date any time soon.

Thanks, at the end every primitive type should be supported without string conversion. The most common use case for users is to use only strings. It is strange numbers are converted to strings and booleans are not supported. But I understand it could sound strange for an internalisation package.
"String"-> String
10 -> num (int|double|num) num extends both
true -> bool
and so on.
