Increment version after filename update and publish to npm

[vincentiusdaniel0]

Hi, could you please increment the package version from 2.0.1 to e.g. 2.1.0 after your update regarding filename property for the generated sitemap? I am using your package through npm, and apparently it does not recognize your latest added feature due to the same version number.

Thanks in advance, this is a very useful package!

(and publish it again to npmjs after that)

Thanks!
