refactor(dash-spv): network manager refactor and sync pipelines optimized

[ZocoLini]

Incredible big PR that does many things to get to a point where the sync time is as low as possible, I will be working on refactoring and cleaning the introduced code in the next PRs but since we need a fast sync for a good user experience at the iOS release I would like to get this merge as long as it can sync

• New dash-spv-bench crate that I used tot set different scenarios and be able to optimice and validate my changes|
• New non-pub NetworkManager that is able to efficiently distribute work
• Mechanism to connect to extra peers when under heavy load
• Sync pipelines no longer wait for item to be stored to disc, they step forward as soon as the item they need is in memory
• NetworkMessages enums fields in dashcore are being stored Behind a Box structure, to reduce memory consumption during sync
• Items are stored to disc as soon as they arrive to avoid high memory usage
