// Package protocol contains functions for performing protocol detection.
//
// # Confidence scores
//
// All registered detectors in this package shall output a confidence score. If there are multiple
// matching protocols, the protocol with the highest confidence score will be returned to the
// caller.
//
// Confidence scores should be between 0 and 0.99, but there is no hard enforcement of this range
// in this package.
//
// # Protocol matching
//
// The first level matching happens with  magic strings, as inspired by Go's [image.RegisterFormat]
// function. The only addition that this package has made, is that you can also use the '*'
// character for wildcard matching.
//
// The supported magic strings input is documented in the [Match] function.
//
// # Strict mode
//
// Some parser also allow for strict parsing of the protocol, which results in a higher confidence
// score, but it also may lead to more false negatives. If [Strict] mode is enabled, then only the
// detectors that support strict checking will be used for protocol detections.
