Update the plugin for Chunky 2.4.0 (#24)

* Add support for Chunky 2.4.0, save denoised images in the snapshot directory.

* Enabled Headless Mode (Untested)

All I did was stop the check for headless from returning, it still warns the user that it may not work.

* Make the plugin compatible with Chunky 2.4.0

* Update info on Chunky 1.x vs 2.x

* Revert "Enabled Headless Mode (Untested)"

This reverts commit 06bf34b.

* Fix incomplete sentence

* Cleanup imports

 # Denoising Plugin
 
-This is a plugin for [Chunky][chunky] that creates _Portable Float Map_ files (.pfm) for use with denoisers, e.g. [Intel Open Image Denoise][openimagedenoise]. The plugin was compiled for and tested with Chunky 1.4.5 as well as Chunky 2.0-beta6.

 To view the resulting image, it needs to be converted back to an actual image file. This can be done by the `pfm2png.py` Python 3 script included in this repository or using an online converter, e.g. [this one][convertio].
 
-## Building the plugin
