Add configuration struct (#66)

[alexiscreuzot]

This is my PR allowing to make reports lighter. I deviated a bit from my original proposition.

Changelog

Added a way to configure logs maximumSize as well as maximumNumberOfSession through a DiagnosticsConfiguration struct.

• maximumSize property allow to change the actual size of the log file
• maximumNumberOfSession allow to limit the number of sessions logged. If you set that value to nil, no limit will apply.

You can use it likes :

let configuration = DiagnosticsConfiguration(
    maximumSize: 1 * 1024 * 1024, // 1MB
    maximumNumberOfSession: 10)
do {
    try DiagnosticsLogger.setup(configuration: configuration)
} catch {
    print(error.localizedDescription)
}

This is a non-breaking change, as using DiagnosticsLogger.setup() will use the default configuration, which is the same as the current one (2MB maximum size, no maximumNumberOfSession)
