Update imgparse to v1.18.1 for quicktile compatability

What?

Update imgparse library to newest v1.18.1.

Why?

This prevents a package conflict in the quicktile-ms-wrapper library between quicktile and radiometric corrections:

INFO: pip is looking at multiple versions of imgcorrect to determine which version is compatible with other requirements. This could take a while.

The conflict is caused by:
    quicktile 2.6.4 depends on imgparse 1.18.1 (from git+https://github.com/SenteraLLC/py-image-metadata-parser.git@v1.18.1)
    imgcorrect 1.7.5 depends on imgparse 1.15.2 (from git+https://github.com/SenteraLLC/py-image-metadata-parser.git@v1.15.2)

To fix this you could try to:
1. loosen the range of package versions you've specified
2. remove package versions to allow pip attempt to solve the dependency conflict
