Releases/v0.6.0 (#97)

* Remove UIKit dependency (#90)

* Replace use of UIDevice and use a different non-UIKit source

* Version updates (#91)

* docs: backfill missing inline API docs (#92)

* feat: Foundation Measurement API for chunk size (#94)

* refactor:  Respell Version to SemanticVersion for explicitness in API (#95)

* Rename revision to patch as in SemVer 2.0.0

* Rename Version to SemanticVersion for explicitness

* Inline API docs and adjust indentation to match rest of the package
