Description:

Start a small Jupiter Perps API. For a start it will be placed in the NenjimHub repo and later moved to its own project upon maturity.

Packages:

API: com.r35157.libs.jupiter.perps
Anchor IDL implementation: com.r35157.libs.jupiter.perps.impl.anchoridl
Future official API implementation: com.r35157.libs.jupiter.perps.impl.ref

First goal:

Add support for reading a known Jupiter Perps position account and returning a JupiterPerpsPosition with its entry price.

Suggested API:

public interface JupiterPerpsPositionService {
    JupiterPerpsPosition getPosition(ΩJupiterPerpsPositionAccountΩ positionAccount);
}

public record JupiterPerpsPosition(
        ΩJupiterPerpsPositionAccountΩ positionAccount,
        ΩUSDCPriceΩ entryPrice
) {
}

Also add the following new ValueTags to detag.conf:

ΩJupiterPerpsPositionAccountΩ - located under String/CryptoCurrencyAddress/SolanaAddress
ΩUSDCPriceΩ - located under BigDecimal/Price

Non-goals:

No liquidation price yet
No wallet-based position discovery yet
No trading or transaction signing yet
