Not parsing response errors

[elupus]

I started using your library for a windows kernel NUT to HID driver (https://github.com/elupus/nut_hid) .

I was trying to match "Err(ClientError::Nut(NutError::VarNotSupported))" but wasn't getting a match. Printing the error gives this representation: "Client error: Server error: VAR-NOT-SUPPORTED".

I think, but not confirmed this yet. That i'm hitting this line:

nut-rs/rups/src/cmd.rs

Line 146 in b79a6af

_ => Err(NutError::generic(format!(

which doesn't seem to be using the parser here:

nut-rs/rups/src/error.rs

Line 113 in b79a6af

"VAR-NOT-SUPPORTED" => Self::VarNotSupported,
