Associate tokens to an account

Associates the provided Hedera account with the provided Hedera tokens. Hedera accounts must be associated with a token first before you can transfer tokens to that account. The Hedera account that is being associated to a token is required to sign the transaction.
If the provided account is not found, the transaction will resolve to INVALID_ACCOUNT_ID.
If the provided account has been deleted, the transaction will resolve to ACCOUNT_DELETED.
If any of the provided tokens is not found, the transaction will resolve to INVALID_TOKEN_REF.
If any of the provided tokens has been deleted, the transaction will resolve to TOKEN_WAS_DELETED.
If an association between the provided account and any of the tokens already exists, the transaction will resolve to TOKEN_ALREADY_ASSOCIATED_TO_ACCOUNT.
If the provided account's associations count exceed the constraint of maximum token associations per account, the transaction will resolve to TOKENS_PER_ACCOUNT_LIMIT_EXCEEDED.
On success, associations between the provided account and tokens are made and the account is ready to interact with the tokens.
The maximum number of tokens that can be associated to an account is 1,000.
