Support T::Struct prop names

[jscheid]

Describe the bug:

Doesn't currently seem to support T::Struct prop names.

Steps to reproduce:

[1] pry(main)> class X < T::Struct; const :foo, Integer, name: 'bar'; end
=> T::Private::Types::Void::VOID
[2] pry(main)> X.from_hash({ 'bar' => 123 })
=> <X foo=123>
[3] pry(main)> X.from_hash({ 'foo' => 123 })
RuntimeError: Error in X#__t_props_generated_deserialize: Tried to deserialize a required prop from a nil value. [SNIP]
[4] pry(main)> TypeCoerce[X].new.from({ 'bar' => 123 })
ArgumentError: Missing required prop `foo` for class `X` [SNIP]
[5] pry(main)> TypeCoerce[X].new.from({ 'foo' => 123 })
=> <X foo=123>
[6] pry(main)> 

Expected behavior:

TypeCoerce[Struct].new.from should probably behave similar to Struct.from_hash.
