Allow older versions of ghc/bytestring

[harendra-kumar]

streamly-bytestring cannot be used with ghc-9.2.2 or earlier because of the bytestring version constraints on it. And we cannot use earlier streamly-bytestring versions with streamly-0.9.0. So there is no other way other than using a newer compiler.

Can we check bytestring version in the code and use CPP to support older versions?

However, ghc-9.2.3 and newer can be used, ghc-9.0.x are anyway not much usable due to perf issues, and I am not sure if it is worth supporting ghc-0.8.x unless someone needs/complains.

8.10.7 still has some popularity
