Minimalistic reader and writer for the Whitespace Separated Values format. To read more about the format, check out @Stenway's WSV documentation, or their Videos on the topic of table formats.
NB: This implementation ignores comments! Might add comment support in the future, but wanted it as simple as possible for now.
To use, simply copy either WsvReader.cs or WsvWriter.cs into your project, and call .Read or .Write on them. WsvReader takes a text span, so for strings you need to call .AsSpan() first.
