Failing to generate types for @account-abstraction/contracts

I'm trying to use the ERC-4337 contracts in the [@account-abstraction/contracts](https://www.npmjs.com/package/@account-abstraction/contracts) package.

I've created a simple Hardhat project that attempts to compile and generate types for the @account-abstraction contracts. To replicate, please use the `typechain` branch as that is barebones.
https://github.com/naddison36/abstract-accounts/tree/typechain

When I compile the project using `yarn compile`, I get the following error
```
Generating typings for: 17 artifacts in dir: src/types/typechain for target: ethers-v5
An unexpected error occurred:

SyntaxError: 'from' expected. (4:24)

Interestingly, types are created in the `src/types` and `src/types/types` folders. If I just use the Hardhat typechain plug-in defaults, types are created in `typechain-types` and the project root.


I've kept the installed packages to a minimum to try and isolate the problem
```
npm ls

The typechain config in Hardhat is
