Feature request: support for Firdaria, Marks, and Davison charts

[charolotte]

Hi Kerykeion team,

Thanks for maintaining this great astrology library.

I wanted to ask whether Kerykeion currently supports, or plans to support, the following chart types:

• Firdaria
• Marks Chart
• Davison chart

If some of these are already possible with the existing API, could you point me to the right approach? If not, would this be within the project scope?

Thanks!
