[connector-request] FxFeed

[ombhardwajj]

This is a suggestion to create a connector for FxFeed using the UI Connector Builder.
The website for the connector is https://fxfeed.io/.

Issue : #46947

[ombhardwajj]

The FxFeed connector has these streams

1. latest : Provides the latest currency exchange rate data
2. historical : Provides historical currency exchange rate data for a specific date
3. convert : Converts an amount from one currency to another, optionally using historical rates
4. timeseries : Provides detailed time series data for currency exchange rates

We can specify a default base currency (USD) and also specify some default currencies/symbols (like top 10 most traded currencies) so that user gets data directly regarding those. Obviously user always has the freedom to modify those according to his needs.

We can have various use cases such as historical currency exchange rate analysis, risk assessment, and strategies for currency hedging and derivatives pricing.
