[Bug] ORCA get swap quote not working

[pedroacamargo]

Describe the bug
Swap quote with ORCA dex is not working properly.
When using the method GetSwapQuote(...), an error with message "Conversion not possible" appears.
This is preventing swaps to work properly with ORCA.

To Reproduce
There are 2 ways to reproduce:

• Simple approach: Go to https://magicblock-labs.github.io/Solana.Unity-SDK/ and try to do a swap
• Technical approach: Write the code below and try to do a swap

try {
    TokenData tokenA = await dex.GetTokenByMint("So11111111111111111111111111111111111111112");
    TokenData tokenB = await dex.GetTokenByMint("EPjFWdd5AufqSSqeM2qN1xzybapC8G4wEGGkZwyTDt1v");
    SwapQuote _swapQuote = await dex.GetSwapQuote(
        tokenA.MintAddress,
        tokenB.MintAddress,
        DecimalUtil.ToUlong(amountInSol, tokenA.Decimals)
    );
}
catch (Exception ex)
{
    Debug.LogError(JsonConvert.SerializeObject(ex));
}

Expected behavior
The error comes from the method public static Percentage FromDouble(double dValue) present in src/Solana.Unity.Dex/Math/Percentage.cs
This method should return a Percentage value instead of throwing an error.
