Add EOFTest CLI Support

[benaadams]

Changes

EEST would very much benefit from a CLI launchable EOF fixtures test.

Here are two CLIs on top of @Demuirgos's EOF test work
(1) adds a -e option to nethtest to test a EOFTest
(2) adds a new standalone netheofparse CLI to participate in eofparse fuzzing.
