Compressor error - Githubissues

Patches https://github.com/SpiNNakerManchester/SpiNNFrontEndCommon/issues/1180

Applying 2 rule of optimisation the previous find_merge was reinstated.

The optimised method was renamed find_merge_optimised and also includes some log methods. Is is currently not used.

Applying the third rule of optimisation extra extra test where added / activated existing generate_routing_compression_checker_report can now be activated with cfg "Mapping", "run_compression_checker"

[Mapping] "router_table_compress_as_far_as_possible" and "run_compression_checker" are now both set true if [Mode] mode = Debug

spynnaker_integration_tests/test_onchip_compressor cfg changed to [Mode] mode = Debug (Without the find_merge change this called some of these tests to fail)

while doing that I fixed some other bugs relating to debug

The confusing and overused cfg settings write_routing_table_reports and write_routing_tables_from_machine_reports have been replaced with

write_uncompressed
write_compressed
write_compression_comparison
write_compression_summary

There is a warning if the old cfg settings exist and are false or an Error if they where True (or in debug mode)

The routing_table_from_machine_report removed as it did the exact same thing as router_report_from_compressed_router_tables

All the reading, checking and reporting of routing tables is now OFF by default!
