Allow resourcet-1.3 in broadcast-chan-conduit

[jchia]

There is a breaking change in resourcet-1.3 related to Data.Acquire.ReleaseType where ReleaseException is replaced by ReleaseExceptionWith.

This affects BroadcastChan.Conduit.Internal, which uses ReleaseException, including for constructing a BroadcastChan.Extra.ThreadBracket wherein cleanupForkError does not get the exception to use for ReleaseExceptionWith value construction. Thus, the changes necessary for using resourcet-1.3 are non-trivial and require code changes and not just .cabal changes, and perhaps even BroadcastChan.Extra.ThreadBracket needs to change.

Yeah, that's been a thorn in my side for a while. I was working on a fix at one point, but that got stuck and ended up on the low priority pile for awhile.

Have you decided what designs are acceptable, though? It seems that an interface change in ThreadBracket is inevitable in a new version of broadcast-extra that uses resourcet-1.3.
