Review comment:
I think this config is not required.
For a dataset with a PARQUET file format, an inline log block format of
PARQUET makes sense. Mix and match of base file format and inline log format
does not seem to make writing data or query engine side faster.
So we can have a config - useInlineFiles() - when enabled, the inline file
format will be format and it will have the same format as the base file format.
This needs to be fixed for the dataset so can be from table config.

Review comment:
I think the configs here should match the configs for the dataset base
file format.
Under what case would the user want separate configs for base file and
inline log blocks?
