* `FetchDataColumnSidecars`: If possible, try to reconstruct after retrieving sidecars from peers if not some are still missing. * `randomPeer`: Deterministic randomness. Before this commit, `randomPeer` was non derterministic, even with a deterministic random source. There reason is we iterated over a map (which is fully random) and then stopped the iteration on a chosen random index (which can be deterministic if the random source is deterministic.) After this commit, `randomPeer` and all its callers are fully deterministic when using a deterministic random source. * Fix Potuz's comment. * Fix James' comment. * `tryReconstructFromStorageAndPeers`: Improve godoc.

Added
- In FetchDataColumnSidecars, after retrieving sidecars from peers, if still some sidecars are missing for a given root and if a reconstruction is possible (combining sidecars already retrieved from peers and sidecars in the storage), then reconstruct missing sidecars instead of trying to fetch the missing ones from peers.
