Lens assets are included in a manifest, and each will indicate when that asset will be used by the lens.
Assets can have the following timing values:
required: the lens will definitely request this asset immediately when the lens is applied.
onDemand: the lens may request this asset at some time while the lens is applied.
Depending on the use-case, an application may want to cache both required and onDemand assets for
a particular lens, or may decide to only cache required assets (or cache no assets).
