refactor(snapbox)!: Change try_text to try_coerce

[Muscraft]

This changes try_text into try_coerce to support changing of a Data's underlying DataFormat to more than just Text.

This adds try_coerce which can be extended to allow conversion between different DataFormats. This also adds Data::format which gives the current DataFormat of the underlying Data. This is useful for when you are trying to convert one Data to another Data's DataFormat (actual.try_coerce(expected.format()))
