* Attempt to convert between integer types using `TryInto`-based conversions rather than blanket failing for some source and destination types. * Use `into_uint` instead of `into_int` in `Value` Deserialize implementations for unsigned integer types. Previously, we were converting from signed types to unsigned types using `as`, which can lead to surprise integer values conversions (mehcode#93). Fixes mehcode#352 and mehcode#93

@matthiasbeyer, I've cleaned up my draft implementation and added a few tests. Your review and CI workflow approval would be appreciated. |

No problem! It looks like all checks have passed and it's ready for merge whenever you're ready. It'd be great to get the new tests in before #338 to ensure that the functionality doesn't regress. |

Yes! #338 has to be rebased onto latest master now, of course 😆 |

into_uintinstead ofinto_intinValueDeserializeimplementations for unsigned integer types. Previously, we were
converting from signed types to unsigned types using
as, which canlead to surprise integer values conversions (Deserializing into a type with an unsigned integer doesn't give the expected result #93).
Fixes #352 and #93
