Replace ete3

[KingAkeem]

Issue #268

Changes Proposed

• Replaces ete3 with treelib as the visualization library
• Remove PyQt5, this as a ghost dependency of ete3 so it's no longer needed
• Added some debug logging to the linktree

Explanation of Changes

ete3 has been causing a lot of dependency issues lately and it's overly complex for our needs. I decided upon using treelib because of it's efficiency and simplicity.
