fix(core): Serialization issues (#350)

- [X] Fixes IPAddresses not having enough space
- [X] Streamlines some code
- [X] Fixes base escortables to not load destination tables in a dangerous way.
- [X] Fixes some bad assumptions about resizing buffers
- [X] Fixes little endian issue with circular buffer writer

This doesn't seem to address #349. That issue requires more investigation because I am not seeing where the issue would be.

Closes #347
Closes #322
