Fix bug with "TypeError: fore|back|style() takes no arguments

[Arinffy]

Dear Mr. Corke,

I hope this letter finds you well.

I wanted to inform you that I am currently using a system with Docker-ubuntu20.04 and Python 3.8.5. I am incredibly grateful for your open-source project, roboticstoolbox-python, which I have been diligently studying.

Furthermore, I recently encountered an issue and debugged the fore|back|style errors. I discovered that for known and definite rendering effects, such as text, one can set the color in the form of fore.GREEN. However, for unknown and dynamic content, it is necessary to use fg(set). If this modification is not made, an error occurs when printing (robot). So far, I have not encountered any other anomalies.

If you have any questions or concerns regarding this matter, please do not hesitate to reach out to me via email at Arinffy@outlook.com.

Thank you once again for your valuable contributions to the open-source community.

Yours sincerely,

Arinffy

thanks for your comments. I am really confused about fg vs fore for the colored package. From its CHANGELOG:

[2.0.0] - 2023-06-19

• Renamed functions:
  • fg() to fore()
  • bg() to back()
  • attr() to style()

then later

[2.1.1] - 2023-06-20

Changed
Restored legacy support for version 1.x.x:
Reintroduced fg(), bg(), and attr() functions (to be deprecated in future releases).

Can you give me a small runnable example that shows the problem you are experiencing.
