Subject: [PATCH] Fix crash on mac (and 32-bit iOS?) - don't represent
 SRDelegateAvailableMethods as a bitfield (#530)

* Don't represent SRDelegateAvailableMethods as a bitfield

Since Objective-C uses a signed char for BOOL on some platforms (macOS and 32-bit iOS) packing this into a bitfield doesn't work since when it tries to read the field it looks for the sign bit and fails with an EXC_BAD_INSTRUCTION. This change sacrifices a few bits for the extra portability.

* CR - followup
