Filter FOVs in calc_distance_matrix

[srivarra]

Is your feature request related to a problem? Please describe.

The option to filter FOVs would be a nice addition for the neighborhood analysis workflow, as some FOVs may not be of interest such as controls.

Describe the solution you'd like

Include a FOVs parameter for calc_distance_matrix which will only load the FOVs supplied.

Describe alternatives you've considered

Another other option would be a regex pattern.
