v1.3.8

• The tools download-from-firehose now respects its documentation when doing --help, correct invocation now is firecore tools download-from-firehose <endpoint> <start>:<end> <output_folder>.

• The firecore tools download-from-firehose has been improved to work with new Firehose sf.firehose.v2.BlockMetadata field, if the server sends this new field, the tool is going to work on any chain. If the server's you are reaching is not recent enough, the tool fallbacks to the previous logic. All StreamingFast endpoints should serves be compatible.

• Firehose response (both single block and stream) now include the sf.firehose.v2.BlockMetadata field. This new field contains the chain agnostic fields we hold about any block of any chain.
