Don't parse HTML Content in body cell #1158

This straight up addresses issue #1158 For discussion and reasoning see there

Like I said in the issue :
When you use the [innerHtml] directive, as ngx-datatable does, Angular already sanitizes the html content beforehand, so no vulnerability to XSS attacks.

See:
https://angular.io/guide/security
https://angular.io/api/platform-browser/DomSanitizer

I think this will limit a ngx-datatable feature (direct output of html in a cell) without adding security as expected.
