convert values that look like ints/floats to ints/floats

[cfreifeld]

needed this feature for my project

btw the == instead of === is intentional. known bug: if value is meant to be an octal int (starting with 0), it will be parsed as a decimal int.

Curious if we could get any traction on this issue or #76.

Closing due to age and lack of tests. As mentioned in #76 a breaking change like this would need to be gated behind a config option.
