instead of a BTreeMap. Some tests fail becuase it does not keep the order. The performace is similiar to the BTreeMap: BTreeMap: ```output Requests out: 400847.83/second Responses in: 361008.64/second - Connect responses: 178712.68 - Announce responses: 178730.98 - Scrape responses: 3564.99 - Error responses: 0.00 Peers per announce response: 0.00 Announce responses per info hash: - p10: 1 - p25: 1 - p50: 1 - p75: 1 - p90: 2 - p95: 3 - p99: 105 - p99.9: 293 - p100: 363 ``` HashMap: ```output Requests out: 410866.90/second Responses in: 368759.97/second - Connect responses: 182729.63 - Announce responses: 182390.37 - Scrape responses: 3639.97 - Error responses: 0.00 Peers per announce response: 0.00 Announce responses per info hash: - p10: 1 - p25: 1 - p50: 1 - p75: 1 - p90: 2 - p95: 3 - p99: 105 - p99.9: 297 - p100: 365 ```
This collection uses a faster hasher. The performance is similar. With FxHashMap: ```output Requests out: 398119.46/second Responses in: 358307.63/second - Connect responses: 177148.18 - Announce responses: 177562.09 - Scrape responses: 3597.36 - Error responses: 0.00 Peers per announce response: 0.00 Announce responses per info hash: - p10: 1 - p25: 1 - p50: 1 - p75: 1 - p90: 2 - p95: 3 - p99: 105 - p99.9: 289 - p100: 371 ``` With BTreeMap: ```output Requests out: 400847.83/second Responses in: 361008.64/second - Connect responses: 178712.68 - Announce responses: 178730.98 - Scrape responses: 3564.99 - Error responses: 0.00 Peers per announce response: 0.00 Announce responses per info hash: - p10: 1 - p25: 1 - p50: 1 - p75: 1 - p90: 2 - p95: 3 - p99: 105 - p99.9: 293 - p100: 363 ``` It does not make sense sice the collections is not ordered and the performace is similar.

New torrent repository using a FxHashMap for the peer list instead of a BTreeMap.
WIP: Some tests fail because it does not keep the order. This PR is only intended to check the performance. The performance is similar to the BTreeMap, so replacing it does not make sense if we lose the order. The order makes results deterministic.
