Rainbow CSV plugins

Automatically highlights CSV columns in different rainbow colors for improved readability, using a lightweight WYSIWYG approach that avoids computational overhead, as noted in the philosophy section.

Includes RBQL, an SQL-like language supporting SELECT and UPDATE queries with Python or JavaScript expressions, allowing data transformation directly within Vim without external tools.

Works with commas, tabs, semicolons, pipes, whitespace, and custom multi-character delimiters, and can highlight non-table files like logs or code, as shown in the commands and features.

Core functionality is written in pure vimscript with no additional libraries required, making installation straightforward and performance efficient out of the box.
