Releasing v1.5.3 with new custom predicate

What's new ?

This release includes new predicate implementation named ChainExitERC1155Predicate. Read more about it https://github.com/thesandboxgame/sandbox-smart-contracts/blob/doc/matic-predicate/documentation/drafts/matic/chain_exit_erc1155_predicate.md.

PR #77 had necessary implementation.

Releasing v1.5.2

What's new ?

MintableERC1155Predicate now handles mint(...) during exiting with tokens as mintBatch(...) with single element.

Previously burning single token on L2 & attempting to exit with it used to revert, which was discovered recently & this release has fix for it.

Releasing v1.5.1

What's new ?

Corrected arbitrary metadata deserialisation logic in (Mintable)ERC721Predicate ✅

Releasing v1.5.0

What's new ?

• Now you can transfer arbitrary NFT metadata from L2 to L1, when using plain ERC721Predicate [ Tokens minted on L1 ]
• For MintableERC721Predicate, you can withdraw batch of NFTs, from L2 to L1 [ Tokens generally minted on L2 ]
• With this release we're able to add support for both batch withdraw & arbitrary NFT metadata transfer, in both ERC721Predicate & MintableERC721Predicate

Releasing v1.4.0

What's new ?

• Updated MintableERC721 Predicate which helps in transferring arbitrary NFT metadata from L2 to L1
• Updated RootChainManager contract with some gas saving optimisation [ Thanks to @nachomazzara ]

Releasing v1.3.0

What's new ?

• New predicates for Mintable ERC20, ERC1155
• Now minting ERC20, ERC1155 on Matic first, then exiting those minted tokens ( but not locked on Predicate ) to Ethereum, works
