Investigate removing 'fast-deep-equal' dependency

when removing old transaction builder we can fully remove the `fast-deep-equal` dependency

The only place where `fast-deep-equal` is used is in `Transaction.ts`

```ts
import deepEqual from 'fast-deep-equal';
```

The risk is however that we still want to deeply match the nfts in inputs and outputs when adding sanity checks for token inclusion (see #239)
