feat: Add new file type for data files

[namurphy]

Suggestion

Add a new file type extension for commonly used data files in src/info/filetype.rs.

Description

There are a number of widely used file extensions for data files. These files include text-based data (e.g., .csv or comma-separated value files), binary data (e.g., .hdf5 or .nc for scientific applications), and databases (e.g., .sqlite or .sqlite3. Because using data files is a common occurrence for many of us, it would be quite helpful to have a straightforward way to visually distinguish data files from other file types.

My personal motivation is that while customizing theme.yml, I found myself adding a bunch of different data file types that come up for science and research software engineering, and it was quite tedious having to do this for a wide variety of data file types.

File extensions

Here is a subset of the file extensions that could be added, though it's missing quite a few extensions (especially for databases).

Extension	Description
.asdf	Advanced Scientific Data Format
.bin	generic binary files
.cdf	CDF
.csv	comma separated value
.dat	generic data files
.db	generic database
.geojson	GeoJSON
.fit, .fits, .fts	FITS
.h5, .hdf, .hdf5	HDF5
.ini	INI
.json	JSON
.nc	NetCDF
.npy	NumPy array file
.npz	NumPy compressed archive
.parquet	Parquet
.pkl	Python pickle
.shp, .shx, .dbf, .prj	ESRI Shapefile
.sqlite, .sqlite3	SQLite
.tsv	tab separated value
.toml	TOML
.yaml, .yml	YAML

Thank you!

I think it'd be nice as well to allow users to group any sets of extensions in a file type rather than each individual ext. Perhaps also use an individual file just so that everyone can copy to 'import' their own file types. Without touching the internal of eza, which is usually complicated.
