[FEATURE] all uncompressed file sizes for different scale factors

I computed the file sizes for scale factor 1 as follows:

```python
import pandas as pd

def get_mem(df):
# Get memory usage in bytes
memory_usage = df.memory_usage(deep=True).sum()

print(f"Memory size: {memory_usage:,} bytes")
print(f"Memory size: {memory_usage / (1024**2):.2f} MB")

df = pd.read_parquet('building.parquet')
get_mem(df)
```

Here are the file sizes for SF1:

| Table | Size (sf1) |
|----------|------------|
| building | 4.06 MB |
| customer | 9.30 MB |
| driver | 0.15 MB |
| trip | 3547.67 MB |
| vehicle | 0.02 MB |
| zone | 1388.61 MB |

Perhaps we can expose a helper to fetch the uncompressed data size and add this info to the documentation?
