Support reading YAML files
Would be cool if pandas supported reading YAML files.

#### Describe the solution you'd like

`pd.read_yaml(file_path: str, **kwargs: dict)`

#### API breaking implications

None

#### Describe alternatives you've considered

You can of course import the `yaml` module, use it to read the file and then feed that data into pandas.

```py
import pandas as pd
import yaml

with open("data.yml") as stream:
    data = yaml.safe_load(stream)

df = pd.DataFrame(data)
```

But for a format that has become as widely used as YAML, this is a lot of manual work compared to

```py
import pandas as pd

df = pd.read_yaml("data.yml")
```
