//! `io` — format readers/writers (IRAP, ZMAP, CSV, LAS, Excel, vector). Wraps
//! external crates behind petekIO's own types. Imports only from `foundation`.
/// Decode bytes as **ISO-8859-1 / Latin-1**: each byte maps to the Unicode code
/// point of the same value. Petrel exports are Latin-1/Windows-1252, so this
/// preserves Norwegian characters (`ø`/`å`/`æ`, `0xC0–0xFF`) that UTF-8 decoding
/// would replace with `�`. (Windows-1252 differs only in `0x80–0x9F` punctuation,
/// not letters, so this is exact for names.)
