atc transactions sent

Fix the Bug Submission Pull Request

What was the bug?
atc.addTransaction({txn: ptxn1, signer: sender})
atc.addTransaction({txn: ptxn2, signer: sender})

property signer can not be assigned by sender, type error

The warning given by VS Code is:
Type 'Account' is not assignable to type 'TransactionSigner'.
Type 'Account' provides no match for the signature '(txnGroup: Transaction[], indexesToSign: number[]): Promise<Uint8Array[]>'.ts(2322)
signer.d.ts(38, 5): The expected type comes from property 'signer' which is declared here on type 'TransactionWithSigner'
(property) TransactionWithSigner.signer: algosdk.TransactionSigner
A transaction signer that can authorize txn

How did you fix the bug?
Opening signer.d.ts, I found the following function
export declare function makeBasicAccountTransactionSigner(account: Account): TransactionSigner;
Using that function, I created a signer, and used that signer in atc.addTransaction:

const signer = algosdk.makeBasicAccountTransactionSigner(sender)
atc.addTransaction({txn: ptxn1, signer: signer})
atc.addTransaction({txn: ptxn2, signer: signer})
