Search and fit multiple 2D circles on a point cloud layer from a single tree, i.e. a forked stem segment.

)LAS object.
numeric - pixel side length to discretize the point cloud layers while performing the Hough Transform circle search.
numeric - largest tree diameter expected in the point cloud.
numeric - use only estimates with more votes than votes_percentile.
numeric - between 0 and 1 - minimum point density within a pixel evaluated on the Hough Transform - i.e. only dense point clousters will undergo circle search.
logical - plot the results?
