Fails to Generate .pb.ts Files With Custom Root Defined

[arranf]

yarn twirpscript fails to generate .pb.ts files when a custom root is defined in a .twirp.json file.

Configuration

Node: 14.17.0
Twirpscript: 0.0.38

A .twirp.json file with the following configuration:

{
   "root":  "./protos"
}

A project of the following folder structure

The Problem

In cli.ts protosBeforeCompile and protosAfterCompile map over the list of file paths to make them relative before passing them to a checksum function which reads them from disk. This relative mapping produces invalid filepaths.

For example, the path exampleservice/haberdasher/v1/exampleservice.haberdasher.v1.pb.ts becomes ../exampleservice/haberdasher/v1/exampleservice.haberdasher.v1.pb.ts.

The Solution

It appears removing this mapping works for both my use case with a custom root defined as well as generation without a custom root defined.
