Bench (#124)

* Add load_matrix_market()

* Add load_graph for vector<vector<tuple<int,int>>> & compressed_graph

* Use load_graph() in mm_bench_dijkstra

Cleanup unused code

* Use new load_graph with dijkstra benchmarks

Refine visitor_dijkstra & co_dijkstra to be closer to BGL impl

* Misc improvements

Added formatters for mm types
Sources in Floating Point are converted to ints

Builds & runs in Windows & Linux

* priority_queue wasn't comparing distances

* Output benchmarks for all sources

* Add examine_vertex as benchmark option

* Refinements to benchmarking

* Enable nwgraph algo for benchmarking

* Add output_algo_results class

* Add option for inline relax_target()

Tighten up options for benchmark options by moving macros & variables
to beginning of mm_bench_dijkstra.cpp so they aren't missed as easily.

* Fix gcc warnings

* Attempt to defined queue as parameter in dijkstra_with_visitor

* Move visitor param after weight function

Rename g_ to g in dijkstra_with_visitor

* Minor changes for vistor_dijkstra

* Fix issues for gcc

Upgrade to fmt 11.0.2

* Use fmt::format instead of std:;format

For some reason the Mac & coverage builds fail when #include <format>

* Replace std::format with fmt::format

* Disable benchmark code by default

Requires C++23 zip; not avail on mac or coverage
