Cargo Features

Loam has no features set by default.

[dependencies]
loam = { version = "0.3.0", features = ["crc"] }
crc = crc32fast

Affects common::CRC_SZ, common::checksum

Features from optional dependencies

In crates that don't use the dep: syntax, optional dependencies automatically become Cargo features. These features may have been created by mistake, and this functionality may be removed in the future.
