Batched contract calls specification

Why

Batched Contract Calls (BCC) allows smartweave users to interact with many contracts using one transaction. It opens possibilities for one-time FCP (Foreign Call Protocol) execution, significantly increases time of calling contracts that require consistent execution, allows to do transfer of PST (Profit Sharing Tokens) to buch of addresses at once.

Suggested implementation

To call contract, program digs all transactions with tag "Contract" that equals to contract initial state transaction id.

Transaction can have many "Contract" tags, each "Contract" tag has own index.

Tags are sorted by position in transaction header (from low to high positions).

Each "Contract" tag should have "Input" tag that is linked to "Contract" tag by index (1st "Contract" tag is linked with 1st "Input" tag).

"Input" tags are sorted same way as "Contract" tags, by position in transaction headers.
