Subject: [PATCH 1/2] Linter configuration for golangci-lint added

This is motivated by #89 to document the target baseline for linting.
It intentionally avoids enforcing linting for changes prior to the
introduction of this configuration so that the project can be
incrementally brought in line.

Each linter is explicitly enabled so there are no surprises if the
defaults are changed.

Only simple formatters are included since the needs of this project
are relatively simple.

Subject: [PATCH 2/2] GitHub Actions workflow to run golangci-lint added

This workflow derives from the recommendation [1] to run a separate
linting job in parallel with other jobs (i.e. tests).

Only new issues will be included until the rest of the repository has
been brought up to date with the new linting rules.
