add pip install to readme.txt

Hi, thanks for this awesome project just note that some things are missing in the "Read Me" file

1. In order to install all the required directories you must enter the command:
   pip -r install requirements.txt and pip install PySimpleGUI

And then run the jumpcutter_gui.py file

In addition, I would recommend adding the "Help" file to the Read Me file:

Modifies a video file to play at different speeds when there is sound vs. silence.

options:

• -h, --help

•                     show this help message and exit
  

• --input_file INPUT_FILE

•                     the video file you want modified
  

• --url URL

•                     A youtube url to download and process
  

• --output_file OUTPUT_FILE

•                     the output file. (optional. if not included, it'll just modify the input file name)
  

• --silent_threshold SILENT_THRESHOLD

•                     the volume amount that frames' audio needs to surpass to be consider "sounded". It ranges from  0 (silence) to 1 (max volume)
  

• --sounded_speed SOUNDED_SPEED

•                     the speed that sounded (spoken) frames should be played at. Typically 1.
  

• --silent_speed SILENT_SPEED

•                     the speed that silent frames should be played at. 999999 for jumpcutting.
  

• --frame_margin FRAME_MARGIN

•                     some silent frames adjacent to sounded frames are included to provide context. How many frames on either the side of speech should be included? That's this variable.
  

• --sample_rate SAMPLE_RATE

•                     sample rate of the input and output videos
  

• --frame_rate FRAME_RATE

•                     frame rate of the input and output videos. optional... I try to find it out myself, but it doesn't always work.
  

• --frame_quality FRAME_QUALITY

•                     quality of frames to be extracted from input video. 1 is highest, 31 is lowest, 3 is the default.
