* Represents the log levels
*
* Monolog supports the logging levels described by RFC 5424 {@see https://datatracker.ietf.org/doc/html/rfc5424}
* but due to BC the severity values used internally are not 0-7.
*
* To get the level name/value out of a Level there are several options:
*
* - Use ->getName() to get the standard Monolog name which is full uppercased (e.g. "DEBUG")
* - Use ->toPsrLogLevel() to get the standard PSR-3 name which is full lowercased (e.g. "debug")
* - Use ->toRFC5424Level() to get the standard RFC 5424 value (e.g. 7 for debug, 0 for emergency)
* - Use ->name to get the enum case's name which is capitalized (e.g. "Debug")
*
* To get the internal value for filtering, if the includes/isLowerThan/isHigherThan methods are
* not enough, you can use ->value to get the enum case's integer value.
