Check for OES_texture_float support is not consistent with behavior on Samsung Galaxy S8

[oscarlorentzon]

mapillary-js version: 2.8.0

Steps to Reproduce Behavior

1. Check if MJS is supported on a Samsung Galaxy S8 which does not have the OES_texture_float WebGL extension by calling Mapillary.isSupported()

Expected Behavior

Result should be true because when creating a viewer with default WebGL behavior on the device everything works fine.

Actual Behavior

Result is false because of lack of the OES_texture_float extension support which is currently required.
