Etlhelper

This release is a minor fix to allow the test suite to pass in Python 3.6.

What's Changed
* Py36 fix by volcan01010 in https://github.com/BritishGeologicalSurvey/etlhelper/pull/138


**Full Changelog**: https://github.com/BritishGeologicalSurvey/etlhelper/compare/v0.14.0...v0.14.1

This release adds the following new features:

+ The `generate_insert_sql` function (used by `load`) validates the table and column names used. As these are user-provided they were a potential route for SQL injection attacks. An `ETLHelperBadIdentifierError` is raised on bad input.
+ The `abort_etlhelper_threads()` function has been added. When called, this raises an `ETLHelperAbort` exception at the end of the current chunk. It can be used to cancel jobs that are running in threads, such as in GUI applications. See [README.md](https://github.com/BritishGeologicalSurvey/etlhelper#aborting-running-jobs).
+ `list_row_factory` and `tuple_row_factory` have been added. Data can now be exported as all of the main Python container types e.g. namedtuple, dictionary, list and tuple. Lists are mutable so are convenient to use with transform functions. Tuples are fast to create and access. See [README.md](https://github.com/BritishGeologicalSurvey/etlhelper#row-factories)

This release adds the `table_info()` function that provides basic metadata about the columns in a table. It is useful when browsing data and when auto-generating SQL queries.

This release makes the following minor improvements:

+ `executemany`, `load`, `copy_rows` and `copy_table_rows` return counts of the number of rows that
were processed and that failed
+ `setup_oracle_client` fails gracefully when cx_Oracle is not installed
+ `load` no longer crashes on being passed an empty list
+ ETLHelperConnectionError reports DbParams instead of connection string, to avoid password appearing in logs
