New features and bug fixes

🚀 New features

New visualization functions

• Added show_3D to visualization module. This function rotates the image along two axes and returns a 2D view from an angle for simple viewing with matplotlib's imshow.

New filters

• Added trim_small_clusters. This function allows the removal of all features small than a threshold size.
• Added hold_peaks function: This function finds the highest greyscale value along in each slice along a given axis.
• Added the prune_branches function. Given an image skeleton, this removes all dangling branches.

Improved generators

• Loosened tolerance for polydisperse generator test
• Switched default solver in sphere generator to bisection method
• Enhanced cylinders function to accept length argument

Minor changes

• Changed trim_disconnected_blobs to make a copy of input image
• Allowed get_border to optionally return indices as well as mask
• Cleaned many docstrings throughout package (need to install a spell checker on IDE!)

🐛 Bugfixes

• Fixed bug in snow_extraction that resulted in some negative throat lengths
• Fixed bug in trim_disconnected_blobs. Note this bug was also impacting porosimetry when an inlet mask was provided.
