Flip focus bug
I found a bug where:
- meridian flip is about to go to FLIP_PLANNED
- capture starts a focus on filter change, so guiding goes from guiding to suspended
- capture gets the FLIP_PLANNED, but because guiding is suspended, it sets resumeGuidingAfterFlip to false. capture.cpp line 3636 resumeGuidingAfterFlip = isGuidingActive();
- then focus finishes, guiding is resumed, then eventually flip happens, but because the variable is set that way, guiding doesn't get resumed.
I don't believe there's any circumstance when you'd be in guide suspended and want to stay that way across a meridian flip, so am modifying isGuidingActive to include GUIDE_SUSPENDED.
