Fix Buffer converter matcher being mangled in minimised builds

[noway]

Hi! 👋

Firstly, thanks for your work on this project! 🙂

Today I used patch-package to patch cbor@8.1.0 for the project I'm working on.

Fixes #164

• This fix might have performance implications - but it is passable for my use case.
• There are other converter matchers which might be mangled - but I only fixed Buffer since that fixes my use case

Here is the diff that solved my problem:

       const converter = this.semanticTypes[obj.constructor.name]
       if (converter) {
         return converter.call(obj, this, obj)

Sorry, thought this going to open a PR, opened a proper PR instead in #166
