AutoDeleveraging

AutoDeleveraging encode

Name	Rule
type	1byte with the value 0x0b
accountId	4 bytes
subAccountId	1 byte
subAccountNonce	4 bytes
oraclePrices	31 bytes, encode the ContractPrice and MarginPrice in order, pass the bytes to Rust SDK rescue_hash method
adlAccountId	4 bytes
pairId	1 byte
adlSize	5 bytes, refer to amount pack method in BigUint pack algorithm
adlPrice	15 bytes, encode to big endian bytes, then pass to thepad_front function in Rust SDK
fee	2 bytes, refer to fee pack method in BigUint pack algorithm
feeToken	2 bytes

ContractPrice encode

Name	Rule
pariId	1 byte
marketPrice	15 bytes, encode in big endian, then pass to the pad_front function in Rsut SDK

MarginPrice encode

Name	Rule
tokenId	2 byte, change to u16, then encode in big endian
marketPrice	15 bytes, encode in big endian, then pass to thepad_front function in Rust SDK
