Pulse 0.19.0

PulseCore

• Rename the folder that Pulse creates in Logs/ directory to com.github.kean.logger. Previously, it was using .pulse as a suffix which was conflicting with the extension used for Pulse documents - #48, thanks to Agapov Alexey
• Add filename to LoggerMessageEntity
• Add URLSession configuration information to logged network requests, including httpAdditionalHeaders
• Coalesce disk writes to reduce disk usage
• Perform less work on the logger's caller's thread
• Catch all Objective-C exceptions (just in case)
• Fix a warning that the logger would write into the console during initialization

PulseUI

• [All Platforms] Display additional HTTP headers - #41
