Implement diffing individual data symbols (#244)

Browse Source 
* Implement diffing individual data symbols

* Remove unused code for diffing sections

* Data diff view: Make rows show offset within the symbol, not within the section

* Remove SelectedSymbol enum as it only has a single variant now

* Create fake data section symbols to allow diffing entire sections again

* Fix text sections not having their size zeroed out

* Update test snapshots

* Clean up code for inferring section symbol size

* Fix bug where PPC pool references weren't ignoring section symbols

* Update comment

* Always add unique section symbols for data sections

* Update test snapshots

* Remove unnecessary clone in format! call

* Auto-start mapping for unpaired data symbols
