[holps-7]

Description
This pull request adds the parse_price_feed_updates function in Aptos contracts. This is an implementation of parsePriceFeedUpdates from ethereum's contract pyth.sol.

Changes Made

• Added a new function parse_price_feed_updates to the Pyth Aptos contract.
• The function takes the following parameters similar to its ethereum's counterpart:
  • update_data: a vector of vectors containing update data.
  • price_ids: a vector of containing PriceIdentifiers.
  • min_publish_time: the minimum publish time as a u64.
  • max_publish_time: the maximum publish time as a u64.
  • fee: fee provided to transaction
• The function processes the price feed updates and returns a vector of ParsePriceFeed objects.
• PasePriceFeed struct is defined as:

struct ParsePriceFeed has copy, drop {
       price_identifier: PriceIdentifier,
       price: u64,
       conf: u64,
       expo: u64,
       publish_time: u64
   }

• The function parse_price_feed_updates is public and calls an internal function for further execution parse_price_feed_updates_internal
• This implementation successfully compiles without throwing any errors
