Fix and export `DataProvider` in line with `lwmdb` spec

[griff-rees]

Ideally sources get renamed in line with the spec @mialondon provides for lwmdb. Following issues managing this in alto2txt, adding a process here to fix those fields in line for import into lwmdb is preferred.

Tasks:

• Add a means of only processing these components without needing all other Newspapers data
• Refactor if necessary
• Add tests for these results in tests.test_newspapers.py
• Generate both csv and json results
• Provide that json fixture for lwmdb

Spec to be implemented:

Fixes

`bna` -> `fmp`
`hmd` -> `bl_hmd`
`lwm` -> `bl_lwm`

• fmp: FindMyPast-funded digitised newspapers provided by the British Newspaper Archive
• jisc: JISC-funded digitised newspapers provided by the British Newspaper Archive
• bl_hmd: British Library-funded digitised newspapers provided by the British Newspaper Archive
• bl_lwm: Living with Machines-funded digitised newspapers provided by the British Newspaper Archive

Potential final output

Worth noting the results of this are meant to help address: Living-with-machines/lwmdb#92

@AoifeHughes: I believe the current json output for DataProvider is of this form (will reformat but as a quick example):

Very excited to see this happen in the next few days! Let me know if you have any questions.

Thanks @mialondon: getting close with pull #35

As of merge 5e04814, test results are now up in metadatadbfixtures in the updated-DataProvider-fixtures folder, for both json and csv format. Fixing this has incorporated a number of configuration options, including printing a table to indicate what DataProvider elements are included when run from the command line. It also provides a means for printing other configuration tables.
