Taking over maintainership of 'flexible-defaults'

Fellow Haskell Hackers, I would like to take over the package 'flexible-defaults' [1] on Hackage, which hasn't seen any activity in the last 2 years. There are trivial changes necessary to fix the build of this library with GHC 8.4.x and these changes have even be proposed by other contributors [2], but unfortunately the maintainer James Cook appears to have lost interest in updating this package. I tried to get in contact with James by e-mail but haven't gotten a response for ~3 weeks. Best regards, Peter [1] http://hackage.haskell.org/package/flexible-defaults [2] https://github.com/mokus0/flexible-defaults/pull/6
