Check `CARGO_ENCODED_RUSTFLAGS` of cargo 1.55+, prefer over `RUSTFLAGS` #38

To work around https://github.com/rust-lang/cargo/issues/10321 that occurs with cargo 1.55.0 and later.

Thanks! However, I did also find my own WIP code I had mentioned, now posted as #39. Besides some refactoring, one difference is that I did not use the same split sequence for both environment variables, because Cargo itself treats them differently. In particular, it does not trim or skip empty args, only skipping if the whole variable is empty.

If you have a real workload that needs this, can you see if my change will work for you?

39 is merged and published as 1.1.0, as well as a re-export as 0.1.8.
