Create fromwhere logo

Use figmint itself to do this: $fig\hat{m}int$

1. Make it LaTeX: `fig\hat{m}int`
2. Use the same Calkit green (copied from FastAPI)
3. Create as part of a Calkit pipeline? Maybe that's a little crazy

Code:

```python
from figmint import Figure

f = Figure()
f.add_latex(r"fig\hat{m}int")
f.scale(width="800px")
f.save("logo.png")
```
