Added

• Added OutputStreamFormatter protocol to define formatters for use with byte output stream type Writers.
• Added TextFormat, an implementation of a OutputStreamFormatter that formats its output based on a supplied template (this is the default formatter for Console and File output).
• Added JSONFormat, an implementation of a OutputStreamFormatter that formats its output in standard JSON format.
• Added OutputStreamWriter protocol to define types that write byte streams to their output and accept OutputStreamFormatter types to format the output.
• Added LogEntry tuple type to Writer defining the formal types that a Writer writes.
• Added .buffer option for .async concurrency modes to allow for buffering when the writer is not available to write to its endpoint.
• Added protected data monitoring for FileWriter.Strategy.fixed on iOS for use with AsyncConcurrencyModeOption.buffer(writeInterval:strategy:). This allows TraceLog to be started up before protected data is available on iOS.

Upated

• Requires Swift 5 for compilation.
• Changed parameters to .async to include options for configuration of the mode (.async(options: Set<AsyncConcurrencyModeOption>) and .async(Writer, options: Set<AsyncConcurrencyModeOption>)).
• Changed Writer protocol log() method to write(_ entry: Writer.LogEntry) to make it easier to process messages by writers and formatters.
• Changed Writer return to Swift.Result<Int, FailedReason> to return instructions for TraceLog for buffering and error recovery.
• Changed ConsoleWriter to accept new OutputStreamFormatter instances allowing you to customize the output log format (default is TextFormat.)
• Changed FileWriter public interface
  • FileWriter now requires the log directory be passed in, removing default value of ./.
  • Removed the fileConfiguration parameter replacing with new strategy enum.
  • It now accepts the new OutputStreamFormatter instances allowing you to customize the output log format (default is TextFormat.)
• Changed FileWriter archive file name date format to "yyyyMMdd-HHmm-ss-SSS" (This was done for maximum compatibility between platforms and can be overridden in the FileConfiguration object passed at init.)
• TextFormat to add var encoding: String.Encoding { get } requirement.
• JSONFormat to add var encoding: String.Encoding { get } requirement.
• Renamed AsyncOption to AsyncConcurrencyModeOption.
• Changed OutputStreamFormatter, it now requires var encoding: String.Encoding { get }.
• Renamed FileWriter.FileStrategy to FileWriter.Strategy.
• Renamed FileWriter.Strategy.RotateOption to FileWriter.Strategy.RotationOption.

Removed

• Removed TraceLogTestHarness module.

Fixed

• Fixed logTrace when no trace level is passed. It's now the correct default value of 1 instead of 4 (issue #58).
