Is the point of this to express "no, we didn't forget about this"?

I'm going to remove this, I did not think thoroughly enough when doing this to realise I was just adding the default implementation :) Thanks

I believe it was previously more readable, but we should use write_err!() anyway. I think it's OK to copy-paste the macro?

Done, as suggested. Cheers.
The current display code for `Error` is a little unusual. We typically just implement `Display` and if a `str` is needed use `format!`. Improve the `Error` type by doing - Remove the `as_str` function and implement `Display` directly. - Remove the 'secp: ' prefix of all the error messages. - Use a newly defined macro `write_err` that writes the error if `std` feature is not enabled so that no-std builds do not loose error info. Note: The `write_err` macro is currently being introduced in `rust-bitcoin` also. Elect to just duplicate it here and not share it between the crates.
