Option to autocreate folders if path does not exist

[chendaniely]

While here was mainly used to read data. It's also useful to write data to locations.

However, it's a little clunky to create folders before using here.
For example:

pl.Path(here("./data/f1/f2/n1/n1", warn=False)).mkdir(parents=True, exist_ok=True)
df.to_csv(here("./data/f1/f2/n1/n1/data.csv", warn=False))

Will make sure all the folders for "./data/f1/f2/n1/n1" are created first before writing.
We can save on the explicit pathlib import and make the save a single line if here contains an option akin to create_dirs=True.
It would turn the above code into.

df.to_csv(here("./data/f1/f2/n1/n1/data.csv", create_dirs=True))

The create_dirs parameter would also set warn=False automatically (since you're most likely going to use this idiom to write to a new file).

Not sure this is a good idea and in here()'s scope. Should be the user's responsibility to create the context for here() to work. It's already a one-liner to pl.Path(here("./data/f1/f2/n1/n1", warn=False)).mkdir(parents=True, exist_ok=True). Have the user go through the mkdir ceremony.

I don't think this is in scope
