BUG: blosc:snappy doesn't seem to be supported with blosc=1.19.0
- [x] I have checked that this issue has not already been reported.

- [x] I have confirmed this bug exists on the latest version of pandas.

- [ ] (optional) I have confirmed this bug exists on the master branch of pandas.

---

#### Code Sample, a copy-pastable example
The following example works with blosc=1.18.1 but fails with the latest blosc (1.19.0)

conda install pandas pytables blosc=1.18.1 # works
conda install pandas pytables blosc=1.19.0 # leads to failure

```python
import numpy as np
import pandas as pd

pd.DataFrame(np.random.rand(10, 3)).to_hdf("test.hdf", "df", complib="blosc:snappy")
```

#### Problem description
The error message is

```
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/home/twoertwe/miniforge3/envs/test/lib/python3.8/site-packages/pandas/core/generic.py", line 2490, in to_hdf

    with HDFStore(
  File "/home/twoertwe/miniforge3/envs/test/lib/python3.8/site-packages/pandas/io/pytables.py", line 521, in __init__
    raise ValueError(
ValueError: complib only supports ['zlib', 'lzo', 'bzip2', 'blosc', 'blosc:blosclz', 'blosc:lz4', 'blosc:lz4hc', 'blosc:zlib', 'blosc:zstd'] compression.
```

The change log of blosc doesn't mentioned snappy: https://github.com/Blosc/c-blosc/releases

#### Expected Output

The compression should either work or `to_hdf` should mention that `blosc:snappy` doesn't work with `blosc=1.19.0`.

#### Output of ``pd.show_versions()``

<details>

I installed the latest blosc as above but for some reason  ``pd.show_versions()`` doesn't find it.
