v3.1.0

What's new

• Excel and gzip input - .xlsx and .gz detected from content, so they work over URLs and stdin too
• Per-column filters under each header, with clearable chips for what's active
• Column show/hide, and exports grouped under one Export menu
• Five themes (default, dark, nord, gruvbox, solarized) — picker in the page or --theme; follows the system by default
• --css and --js inline your own stylesheet and script, with the table API on CsvToTable.table. A theme in your CSS joins the picker
• --description, plus Markdown in the title — --title-html/--description-html for raw HTML, @file to read from disk
• Redesigned page - toolbar ordered by use, live row count, csvtotable- class hooks, nothing styled through an ID

Flags

New: --description, --description-html, --title-html, --theme, --css, --js, --no-column-filters.
Renamed, old spelling still works: --page-size (was --display-length), --title (was --caption).

Compatibility

Every v2 flag still works. The title is now an <h1> above the table rather than a <caption> inside it, so it no longer scrolls away from a wide table.
