OpenSpout

I have recently found myself in a situation when 3 out of 4 libraries that I used to work with Excel files were abandoned:

• akeneo-labs/spreadsheet-parser (streaming reader) had no commits in 4 years

• mk-j/php_xlsxwriter (streaming writer) had no commits in 2 years

• box/spout (streaming reader/writer) is formally abandoned

Luckily there exists a community fork of Spout called OpenSpout and it can replace them all. It seems pretty popular with 1 mln downloads and 229 stars but it's still less popular than the original and I managed to find it only by navigating the forks of Spout so I think it just needs more exposure.
