Add transaction tax report

[ZIMkaRU]

This PR adds the Transaction Tax Report

---

Adds two strategies to calculate the user's trades FIFO and LIFO.
FIFO (first-in-first-out) and LIFO (last-in-first-out) are two accounting methods used to calculate cryptocurrency gains and losses, see this article
For conversion currencies are used the Public Trades endpoint of the BFX api_v2: https://docs.bitfinex.com/reference/rest-public-trades

---

Basic changes:

• adds getTransactionTaxReport endpoint
• adds getTransactionTaxReportFile endpoint
• adds makeTrxTaxReportInBackground endpoint
• adds corresponding test coverage

• makeTrxTaxReportInBackground request example

{
  "auth": {
    "token": "user_token"
  },
  "method": "makeTrxTaxReportInBackground",
  "params": {
    "start": 1706861968714,

  }
}

• makeTrxTaxReportInBackground response example

{
  "jsonrpc": "2.0",
  "result": true,
  "id": null
}

The idea of the makeTrxTaxReportInBackground endpoint is the following:

• the big users may have a lot of trades for a certain year

• to convert currencies to USD are used the public trades endpoint of the BFX API with 15reqs/min rate limit

• it can lead to significant time in report generation

• to fight HTTP timeout for this case, it is necessary to send makeTrxTaxReportInBackground HTTP request to schedule generation

• and when the report generation is successful the data of the tax report will be responded via WebSocket

• emitTrxTaxReportGenerationInBackgroundToOne WS event example:

{
  "jsonrpc": "2.0",
  "result": [
    {
      "asset": "LTC",
      "amount": 1.43796106,
