CRAN urgently needs update with working maintainer address

[kurthornik]

We recently checked whether the maintainer contact address for package
'flourishcharts' is still up to date (as mandated by the CRAN Policy),
but unfortunately email to this address bounced.

We urgently need an updated version on CRAN (with a new version number)
with a working maintainer address.

Please provide a fixed version as soon as possible.

Please see https://cran.r-project.org/web/checks/check_results_flourishcharts.html
for other issues that may need addressing.
