Package entropy provides the passive entropy source for the FIPS 140-3
module. It is only used in FIPS mode by [crypto/internal/fips140/drbg.Read].
This complies with IG 9.3.A, Additional Comment 12, which until January 1,
2026 allows new modules to meet an [earlier version] of Resolution 2(b):
"A software module that contains an approved DRBG that receives a LOAD
command (or its logical equivalent) with entropy obtained from [...] inside
the physical perimeter of the operational environment of the module [...]."
Distributions that have their own SP 800-90B entropy source should replace
this package with their own implementation.

Package-Level Functions (only one, which is exported)
Depleted notifies the entropy source that the entropy in the module is
"depleted" and provides the callback for the LOAD command.
