Luke Street 424434edd6 Experimental ARM64 support 
Based on yaxpeax-arm, but with a heavy dose of
custom code to work around its limitations.

Please report any issues or unhandled relocations.

Luke Street 21f8f2407c Relax symbol comparison logic 
The Ghidra delinker plugin emits functions with type STT_OBJECT,
rather than STT_FUNC. The current logic was preventing these from
being compared based on their symbol type. Relax this condition
for now.

Improve dependency gating on objdiff-core (#126) 
* Reduce dependencies for no features

* Add missing deps to every feature

* Add missing `dep:`s

* Gate even more deps behind features

Removes dependency on tsify-next / wasm-bindgen unless
compiling with the wasm feature by using `#[cfg_attr]`

* Fix wasm

Fix data tooltip panic (#123) 
* Fix data tooltip panic

Prevents panicing when attempting to display the data tooltip for a symbol that is too large by just using as many bytes as needed from the begging of the symbol.

* Don't attempt to interpret wrongly sized data

* Reference data display improvment issue

* Log failure to display a symbol's value

Add symbol mapping feature (#118) 
This allows users to "map" (or "link") symbols with different names so that they can be compared without having to update either the target or base objects. Symbol mappings are persisted in objdiff.json, so generators will need to ensure that they're preserved when updating. (Example: d1334bb79e)

Luke Street b4650b660a Hide auto-generated objects in object list

in objdiff.json for reporting
purposes, so this maintains the
existing behavior.

Luke Street cad9b70632 Support protobuf format for reports 
This migrates to using protobuf to
define the "report" and "changes"
formats in objdiff-cli.

The JSON output now uses the Proto3
"JSON Mapping", which is slightly
incompatible with the existing JSON
format. Mainly, 64-bit numbers are
represented as strings, and addresses
are decimal strings instead of hex.

However, the older JSON format is
still accepted by "report changes"
to ease migration.
