Bug: README instructions for base24.py do not match current installed script requirements

[N0NB]

Before You Begin

Before proceeding, please make sure to follow these steps:

• I have checked for similar issues in the project's issue tracker.
• I have searched closed issues to see if a similar problem was reported
  before.

Issue Details

The README instruction of base24.py update fails.

Description

I was led to this repository from the https://github.com/tinted-theming/base24-gnome-terminal repository as it is out of date and lacks many themes currently in tinted-vim and tinted-shell, etc. Attempting to follow the instructions led to a few false starts, but I think I finally managed to run dropin.py from the right directory and then base24.py (without a command) and both appeared to succeed after installing the needed Python modules.

Expected Behavior

I expected to be able to update the themes.

Actual Behavior

base24.py update generates the following error:

$ python base24.py update
usage: base24.py [-h] [--schemes-dir SCHEMES_DIR] [--verbose] [--online] [--config CONFIG]
base24.py: error: unrecognized arguments: update

Running base24.py -h results in:

$ python base24.py -h
usage: base24.py [-h] [--schemes-dir SCHEMES_DIR] [--verbose] [--online] [--config CONFIG]

options:
  -h, --help            show this help message and exit
  --schemes-dir SCHEMES_DIR
                        Target directory for scheme data
  --verbose             Log all debug messages
  --online              Run in online mode and pull schemes directly from GitHub
  --config CONFIG       Configuration

It seems to me the script has changed considerably since the README was last updated.
