Hello!

Suppose I have a folder structure given as:

TopFolder

- A
- B
- C

Where parquet files are stored inside of A,B and C.

I know that if I do:

```julia
Parquet2.Dataset("TopFolder")

```

Then it will have access to all the parquet files in A,B,C. I know that if I do:

```julia
Parquet2.Dataset("TopFolder/A")

```

Then it will only read the parquet files in A.

Suppose I only want to read parquet files from the folders; A and C.

How to do that?

Kind regards
