InternetLines v0.3.0

The release changes the interface for Collection-based line parsing.

• The computed property to access line parsing for Collection types is renamed to internetLineRanges. This fixes the confusion from Collection.internetLines having an incompatible element type despite sharing a name with the Sequence and AsyncSequence versions. Collections now can use the Sequence-based parser without AnySequence wrapping.
• Change the element type for the Collection line parser from a tuple to a custom value type. This type lets the user decide whether the line range includes or excludes the terminator.
