Use Rust erasure library and turn on erasure (#3768)

Browse Source 
* split out erasure into new crate; add implementation using rust reed-solomon-library

* Track erasures with a &[bool] instead of indexes

* fix bug that reported the number of erasures incorrectly

* Introduce erasure `Session` for consistent config

* Increase test coverage; fix bugs

* Add ability to remove blobs from erasure meta tracking. test added

* Track deletion of coding blobs in blocktree via ErasureMeta. Added to
test

* Remove unused functions in blocktree

* add randomness to recovery thread to exercise recovery due to either new
data or coding blobs

* Add unit test for ErasureMeta index handling

* Re-enable test in broadcast stage
