this will be used for a help screen, which isn't done yet, but this
makes the edit screen incrementally better too

this tree UI allows for viewing and basic editing of a configuration
section from a board. it does a decent job of displaying most of the
settings, and editing is equally convenient, as in it tries to handle
enums correctly, but doesn't validate pins or handle long binary strings
well.
saving is done in place --- if a config/storage section was opened, a
config section (no padding) is what results. if a whole board was
opened, the whole binary is rewritten with the new offset config
section. this way, a whole board dump can be changed in place, or a new
config can be made for use in e.g. concatenate to build an image
many enhancements to come over time
