Conversions for HDR Canvas Specification

Hi all,

I've added a list of suggested colour forward and reverse transforms between extended-sRGB, extended-linear-sRGB and bt2100-hlg and a suggested simple tone-mapping for displaying bt2100-hlg on an sRGB display to issue #50 -  I've tried to follow the style of the example in TTMLv2 provided by Pierre.

I can recalculate the matrices to a different number of significant figures if necessary - is there a consensus on accuracy levels for web operations?

Would Dolby colleagues be able to add the bt2100-pq versions to the list?  There is a PQ example in Pierre's TTMLv2 link.

Best Regards
