enable usage with non-nightly rust

[haraldh]

default is "nightly"

to compile with stable rust:
x86_64 = { version = "0.9", default-features = false, features = [ "stable" ] }

Thanks a lot for the PR! The changes mostly look good to me, apart from the comments I left.

Also, we should adjust the CI to also build without the nightly feature and with the stable feature.

Another thing: What happens when the user enables both the nightly and stable features? I expect there will be some duplicated function errors. Perhaps it's possible to add a custom error message for this case?

if "nightly" and "stable" are enabled, then it results in "nightly"

if "nightly" and "stable" are enabled, then it results in "nightly"

which is nice, as one can start with "stable" and add "nightly" as part of other feature sets

Makes sense!

left out windows.. don't know how to install the needed toolchain

Thanks for the update! Looks good to me now.

It would be nice if you could add a short section about the nightly and stable features to the README. We should also mention that the stable feature is only tested on Linux and macOS.
