Export data from SQL databases in various formats.

Currently supported database drivers:

• PostgreSQL (via SQLx);
• MySQL (via SQLx);

Currently supported file formats:

• XLSX (via rust_xlsxwriter);
• JSON (via serde);
• GFM tables;

Development is in very early stage but could be useful for quick database export in XLSX and for embedding tables in markdown docs.

Planned file formats support:

• CSV;
• SQL "INSERT INTO";
• SQL "LOAD DATA INFILE" / "COPY FROM";
• Bincode;
• Apache Arrow IPC;

Planned database driver support:

• SQLite (via SQLx);
• PostgreSQL (via tokio-postgres);
• MySQL (via mysql_async);
• MSSQL (via tiberius);

• GFM: column alignment;
• Limit useless string allocaations (via Cow / flexstr);
• Use rayon to improve speed;
• Custom formats via options (especially for xlsx/gfm);
