Flareon

Compatibility with previous version is broken, again yes I'm sorry but this is the last time

Change:

• all post-detection operation (extract, filter, split, scrubb) are now subcommand
• chimeric-threshold option is renamed coverage
• not-covered-threshold option is renamed not-coverage
• memory usage is reduced but the length of read need to be lower than 2^32
• add an ondisk mode to reduce again the memory usage, on this mode memory usage is linear in the number of read, in basic mode memory usage is linear in the number of overlap
• more understandable error messages

Thanks to Peter Ebert (for the idea of disk mode), Luiz Iber (for niffler, and discovering of many useful crates), and all people they found bug in development and previous version.

It's probably the last version before 1.0
