1.14.5: Convenience, appearance improvements; bugfixes

FEATURES:

• Added bordercolor kwarg to features_2D which allows setting color of border lines, useful when images are majority-dark
• Improved xaxis annotation handling for pad_xticks kwarg in features_hist and features_hist_v2; behavior configurable via configs['pad_xticks']
• show_xy_ticks can now be an int or bool, which will automatically set to tuple (int, int).
• Changed default kwarg timesteps_xaxis to False in features_2D which would rotate image data

BREAKING:

• pad_xticks is now bool instead of int

BUGFIXES:

• features_2D: moved ndim != 3 check outside of timesteps_xaxis, which would fail to expand_dims(0, ...) for =False w/ 2D input
• weights_norm: the case of one weights per layer would process incorrectly due to iterating over an expected list, where get_weights returns the array itself in case of a single weight

MISC:

• Added test cases to account for fixed bugs
