Removed --assume_unmapped_paired option as it is now the normal behaviour.

Only override RG tag in bridge with original if --ignore_rg is set, because
otherwise it is already part of the equality comparison.

Include RG in uid even if ignore_rg is set (because RG should always be in original)
Fixed bbr_hashcode to use a tablesize of SIZE_MAX instead of sizeof(size_t)
Added tracking and reporting of maximum reads in buffer during processing.

Eliminated repetitive calls to gl_list_size
Initialised fp to 0
Added original_refid and original_pos to binnie_binned_read_t

Updated bbr_init to set original_refid and original_pos

When bridge_read is set, overrides original_* with those from the original read

Changed refid and pos checks to use these as well.
