Made several modifications to fix all timing violations to run compressor @250MHz - 1.0 Gigapixel/sec in JP4 mode

implemented optional skipping/fast forward of the data blocks when buffer is over/underrun during memory access

added simuilation modules for frequency multiplication/division, fractional period delays, started parallel12 -> HiSPi packetized SP converter

Working on cmprs_afi_mux.v, extracted 2 sub-modules: cmprs_afi_mux_ptr.v and cmprs_afi_mux_ptr_wresp.v

Fixed handling AXI write responce channel - both in work and simulation modules. Before each word, not burst was responded
