2.0.0

Major overhaul, both internally and in terms of the library interface. The library is rewritten in its entirety. See the documentation at https://scnlib.dev/, namely the Migration guide for more details.

The changes below are relative to v1. See CHANGELOG.md for changes relative to v2.0.0-beta.

Major changes include:

• C++17 is required.
• Several names are changed to include the scan_ prefix.
• scn::scan returns the scanned values by value. Output parameters are no longer used.
• scn::scan now accepts all forward_ranges (v1: bidirectional_range + default- and move constructible).
• scn::scan returns a view (subrange) into its input, and never takes ownership.
• Scope is more focused: list operations, ignore, getline, and file have been removed.
• Support for regular expressions.
• Better Unicode support.
• Performance improvements.
• Completely reworked internals.
