Subject: Add runtime encoding detection and conversion 	Win-1251/1252
 detection is a reduced C++ version of https://github.com/hsivonen/chardetng
 Add manually-specified encoding fallback Add default system encoding fallback
 Add error recovery to v2script Add unknown encoding detection warning Remove
 csv::Parser templating Fix lua files dropping data

Update lexy to foonathan/lexy@1e5d99fa3826b1c3c8628d3a11117fb4fb4cc0d0

Remove exclusive reliance on lexy::default_encoding for v2script

Move internal concepts to src/openvic-detail/InternalConcepts.hpp
Move contents of DetectUtf8.hpp to src/detail/Detect.hpp
Move openvic-dataloader/AbstractSyntaxTree.hpp to src
Move DiagnosticLogger.hpp to src
Move File.hpp to src
Move openvic-dataloader/detail/utlity files to openvic-dataloader/detail

Add ovdl::utility::type_concat
Add ovdl::utility::type_prepend
Add ovdl::utility::is_instance_of
Overhaul parse error messages
