Package MarkerMap for local installation

[WilsonGregory]

Changes

• add MIT license, fix for: https://github.com/Computational-Morphogenomics-Group/MarkerMap/issues/18
• add files to allow creating a package for the code
• update the benchmark_k script to import the package without having to add it to the path
• update the notebooks to import the package without having to add it to the path
• I did not update the notebooks Array_of_Markers and DemoSimpleInterface because they are on colab, so they need to be able to install the package from pip before we can swap over (as far as I am aware)

Testing

• run through select portions of the notebooks to make sure the imports work correctly
• run through the benchmark script to make sure the imports work there
• future testing: Do a fresh install following the instructions to make sure they work correctly
• ran unit tests

Doc Changes

• some updates to the readme, specify locally installing the package
