//! Era and Era1 files support for Ethereum history expiry.
//!
//! Era1 files use the same e2store foundation but are specialized for
//! execution layer block history, following the format:
//! Version | block-tuple* | other-entries* | Accumulator | `BlockIndex`
//!
//! Era files are special instances of `.e2s` files with a strict content format
//! optimized for reading and long-term storage and distribution.
//!
