Fix endmembers

Fix the endmembers to a set of samples. Apply the clustering to group all the signatures to the selected endmembers.

signatures <- unmixing_fixed(
  signatures, 
  endmember_files=c("signature0000.asd", "signature0001.asd", "signature0002.asd", "signature0003.asd", "signature0005.asd"),
  endmember_names=c("orange", "red", "black", "white", "base"),
  endmember_colors = c("darkorange2", "red2",  "gray15", "white", "green4")
)
signatures <- clustering_endmembers(signatures)
