Is your feature request related to a problem? Please describe.
My app supports entering enigo commands as a ron-serialised array. People often make mistakes like not capitalising alt or shift as Alt or Shift.

Describe the solution you'd like
Configuration of serde to accept more variation in deserialisation.

P.S. I see the source has been bumped to 0.4.0, but it's not released on crates.io. Will it be out soon? (people want Function keys on Linux)
