Language server crashes on hover

[slavek-kucera]

Describe the bug
The language server may crash when hovering over a macro that had been opened and closed in VSCode.

To Reproduce
Steps to reproduce the behavior:

1. Open a file with an external macro
2. Go to macro definition
3. Close the newly opened window
4. Hover over the macro in the opencode file

Expected behavior
Do not crash and show useful information about the macro instead.

Additional context
text_data_ref_t looks fundamentally broken - indices are one time computed, but the string content can change.
File versioning should probably be utilized (get_version())
