v0.3.0: Better error-handling with ResExt

What's new

• Added more performant error-handling using ResExt (my new crate)
• Added better error messages with context chains
• Made some errors recoverable (e.g. invalid rows in a CSV file don't stop the conversion and instead aren't included in output)
• Simplified matching logic in main.rs
• Removed the WrtierStreams::Temp {} variant from WriterStreams as it became obsolete with the simplification

---

Changes

Removed verbose flag from convert operations, so this is not valid anymore:

fiox convert <INPUT> -o <OUTPUT> -v

Instead, if you need more verbose error messages you should use:

fiox validate <INPUT> -v

---

Note: The first crates.io release will be on v0.4.0, or on v0.5.0 which will be polish for v0.4.0.
