Small FromArma impl fixes

[Eathox]

Various small things I noticed while working on the trait derive PR, decided to make it a separate PR

• Fix split_array returning a vec with an empty string when parsing a empty array
• Fix greedy string quote trimming; "hello ""John""" previously resulted in hello ""John
• Fix string didn't convert double quotes to single quote
• Remove unnecessary trim calls
• Simplify tuple impl by converting from a fixed sized array
• Implement IntoArma for tuples of up to 26 elements (IntoArma and FromArma didnt support the same count and thought they might as well match)
