CLI Doesn't work with vite-dts, export syntax too new

The rolled up exports uses `export * as ____` syntax and there's no way to turn it off. My type compiler `vite:dts` cannot understand the `index.ts` file that is produced because of this.

See: https://github.com/dethcrypto/TypeChain?tab=readme-ov-file#cli

```
error during build:
Error: [vite:dts] The "export * as ___" syntax is not supported yet; as a workaround, use "import * as ___" with a separate "export { ___ }" declaration
/Users/johnshankman/Documents/manifoldxyz/burn-redeem-contracts/dist/contracts/ethers/index.d.ts:10:8
```

There's no way to control how this is generated using the typechain command

## Solution

Use older `import * as ` syntax with `export` at the end of the file. That way there's 0 chance of ever having compatibility issues with outside packages like vite-dts etc. No need to use new school syntax on such a simple file being autogenerated.
