NLS: Remove strange dead_cedilla cedi sign sequences

These sequences appear to be a leftover artifact of auto-generating dead_currency sequences for cent and the cedi sign, where chaining with ascii "c" vs "ccedilla" would output cent vs the cedi sign respectively, but somehow this ended up creating strange sequences with dead_cedilla followed by cent or the colon sign to output the cedi sign, the latter sequence of which was already removed recently. Additionally, sequences beginninng with dead_cedilla followed by currency have been removed as they also appear to be related to these artifacts. The two remaining sequences beginning with dead_currency followed by dead_cedilla are maintained and moved to the stretch of dead_currency sequences next to ccedilla, and sorted in order of unicode decompositional complexity.
