scribe 0.3.0

Breaking changes

$convert field now defaults to the newly exported scribe_convert() helper
- This selects one of three conversions: 1) default (see next bullet), 2) string evaluation, and 3) no conversion.
- default conversions use value_convert(), which internally uses utils::type.convert() (and some additional steps for dates. Be aware that type.convert("1", as.is = TRUE) will return integers, and a decimal should be included if a numeric is desired (e.g., type.convert("1.", as.is = TRUE)
- previously, a prototype could be set (e.g., convert = character()), which will now fail but can be replaced with a simple function (e.g., convert = as.character).
