Tool providing a semantic readout of diffs between "before" and "after" stylesheet states. Assumes stable layer id names.

Currently detects

• changes to all parameters within each style layer
• changes to the layer stack (new, removed, moved layers)
• changes to sources (new, removed, updated sources)

To be implemented

• changes to stylesheet parameters outside layers and sources
• detecting renamed layers (in a way beyond showing them as removed and immediately readded)
