Added proposed features from lsp 3.16 (#230)
* Switched from longs to ints when handling document lines and columns * Added proposed features from lsp 3.16 * Updated capabilities to include the ability to inspect handler descriptors * Added IStringEnumLike to deal with strongly typed strings that behave like enums but can be extended with other values based on clients * Added DocumentUri class to replace usage of Uri. It supports conversion from file system like paths (windows and unix), uri strings (scheme://...) and Uri. In addition it manages the funny serialization that VSCode does in regards to : on windows file systems. Co-authored-by: Tyler James Leonhardt <tylerl0706@gmail.com>
