* 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
