v0.3

This release introduces a new way for merging components that does not require the computation of the residual Y_res, yielding significant gains in speed and memory requirements. The choice for using fast merging can be tuned from options.fast_merge which is set by default to 1. To enable this option the following changes have been made:

• merge_components takes the input data Yr as its first input and not the residual Y_res
• update_temporal_components and update_temporal_components_parallel no longer produce the residual Y_res as an output.
