`jstream` is a streaming JSON parser and value extraction library for Go.

Unlike most JSON parsers, `jstream` is document position- and depth-aware -- this enables the extraction of values at a specified depth, eliminating the overhead of allocating encompassing arrays or objects; e.g:

Using the below example document:

    permissions:
      contents: read
      issues: write
    runs-on: ubuntu-latest

    steps:

        with:
          fetch-depth: 0
      - name: Set up JDK 17
