Work in progress: Improve filestream

[pbricout]

New implementation makes completely isomorphic the read/write sync and async implementation, the only difference in the async implementation are the file calls and the await. The new implementation handles multiple ID3 tags.

Still to do:

• [x] Improve write implementation
• [x] Make buffer size an option for write, write test to cover different code path for writeId3TagToFileSync/Async
• [x] Improve read implementation
• [ ] Refactor common parts of the steam process class
• [ ] Make buffer size an option for read, write test to cover different code path for read
• [ ] Support update
• [ ] Add padding support
• [x] Fix temp file generation, actually Date.now() may generate several times the same file especially when tests are ran in parallel and even more if the precision is reduced
• [ ] Something is broken with Node 10.x I must use a feature not available in node 10.x
