Subject: [PATCH] fix(tsv): honor infer_table_structure when partitioning TSV
 files

partition_tsv() had no infer_table_structure parameter, so the kwarg landed
in **kwargs and was dropped: Table.metadata.text_as_html was always set, even
for partition(..., infer_table_structure=False) or a skip_infer_table_types
list containing tsv. csv, xlsx, docx and odt all gate text_as_html on that
flag; tsv did not.

Adds the parameter with the same docstring as the other partitioners and
gates the html on it, plus the two regression tests the csv and xlsx
partitioner tests already have.

+### Fixes

+- **`partition_tsv()` honours `infer_table_structure`.** The function had no `infer_table_structure` parameter, so the argument was absorbed by `**kwargs` and dropped: `Table.metadata.text_as_html` was set even for `partition(..., infer_table_structure=False)`, or for a `skip_infer_table_types` list containing `tsv`. `partition_csv()`, `partition_xlsx()`, `partition_docx()` and `partition_odt()` all gate that field on the flag, and `decide_table_extraction()` in `partition/auto.py` passes it to every non-special partitioner. The parameter now has the same name, default and docstring as its siblings.
