merge 'fiducials' branch into main

[iamdonovan]

This PR will merge a number of improvements to tools for finding fiducial marker locations in air photos into the main branch.

documentation:

• add a diagram for Fairchild T-11 style cameras with "checkerboard" fiducial markers
• include more detailed tutorial information for using the automated tools

spymicmac.matching:

• adds improvements to find_fiducials, including limiting the search space based on a MeasuresCamera.xml file
• replaces match_fairchild_k17 with match_fairchild, to allow for matching Fairchild-style cameras including KC-1 and T-11
• adds match_wild for matching fiducial marker locations in Wild RC-style cameras
• adds match_zeiss_rmk for matching fiducial marker locations in Zeiss RMK-style cameras
• updates cross_template to allow for a rotated cross shape
• updates wagon_wheel to allow for a rotated wagon wheel shape, as well as a ring that is smaller than the cross

spymicmac.micmac:

• fixes parse_im_meas to read MeasuresCamera.xml files
• adds estimate_measures_camera, for estimating fiducial marker locations in image space based on a sample of MeasuresIm files
• adds batch_saisie_fids, for running mm3d SaisieAppuisInitQT on a list of image filenames

spymicmac.orientation:

• adds a new function, plot_camera_centers, which plots camera center locations read from an Ori directory
• updates transform_centers to allow for shapefiles of camera center locations, not just footprints, to be used

spymicmac.resample:

• adds some initial attempts at aligning images based on common features, such as borders/fiducial markers
