Bigquery-schema-generator

* 1.3 (2020-12-05)
* Allow an existing schema file to be specified using
`--existing_schema_path` flag, so that new data can be merged into it.
See 40, 57, and 61.
(Thanks to abroglesc and bozzzzo).

* 1.2 (2020-10-27)
* Print full path of nested JSON elements in error messages (See 52;
thanks abroglesc).

* 1.1 (2020-07-10)
* Add `--ignore_invalid_lines` to ignore parsing errors on invalid lines
and continue processing. Fixes
[49](https://github.com/bxparks/bigquery-schema-generator/issues/49).
* Add GitHub actions for automated tests and flake8 validation.
* Add package `__version__` string.
* Update setup.py, no longer need to convert README.md markdown to RST.

* 1.0 (2020-04-04)
* Fix `--sanitize_names` for recursive RECORD fields (Thanks riccardomc,
see 43).
* Clean up how unit tests are run, trying my best to figure out
Python's convolution package importing mechanism.
* Add GitHub Actions continuous integration pipelines with flake8 checks and
automated unit testing.

* 0.5.1 (2019-06-17)
* Add `--sanitize_names` to convert invalid characters in column names and
to shorten them if too long. (See 33; thanks jonwarghed).

* 0.5 (2019-06-06)
* Add input and output parameters to run() to allow the client code using
`SchemaGenerator` to redirect the input and output files. (See 30).
* Remove fields with incompatible types (or other errors) from the generated
schema, instead of picking the type of the first encounter. (See 31).
* Improve internal data validation handling, reserving exceptions for
programming errors only.
