v0.19.0

This release introduces the new stream decoder for enex files.
It should improve user experience by processing notes from the export one by one, and skipping the malformed ones.
As a consequence, progress bar is replaced with spinner, since stream decoder doesn't know the total number of notes.

• Fixed Unexpected EOF in CDATA section bug (#16)
• Fixed file extension for JPEG images ( thanks to @karottc for contribution 🏅 #98)
• Updated dependencies
