BTC opcodes still present after tree-shaking

I have a BCH-only project that is packaged with Parcel.

When I run the bundle analyzer I can see both btc and bch opcodes in the vm/instruction-sets:

- bch/2023/bch-2023-opcodes.js
- btc/btc-opcodes.js

I'm not sure if this is intended, or if the btc-opcodes should be tree-shaken and removed from the bundle.
