Install quire-11ty to a project sub-directory

[mphstudios]

Work-in-progress to install quire-11ty to a sub-directory in the project directory.

Intended output—

projectRoot/
├── .git/      <-- repository reset by `quire new` command
├── .gitignore <-- add ignore file pattern for `quire11tyPath`
├── .node-version
├── .quire-version
├── 11ty/      <-- Should this be a hidden (.11ty) or git ignored by default?
