Fix Symbol Possibilites for the Reads

[Parvfect]

All possible symbols compatible with motifs that are encountered - not at a symbol level

[Parvfect]

Take some time and think about it and do it. Here we go.

DONE!! Code is shit and needs to be verified but look at this

The Threshold is around 4 and our decoder performs so much better than BEC! We are onto the finish line boys

Double check this method

def get_possible_symbols(reads, symbols, motifs, n_picks):

    reads = [set(i) for i in reads]
    symbol_possibilities = []
    for i in reads:

        # Will only work for the Coupon Collector Channel
        motifs_encountered = i
        motifs_not_encountered = set(motifs) - set(motifs_encountered)

        read_symbol_possibilities = []

        if len(motifs_encountered) == n_picks:
            read_symbol_possibilities = [get_symbol_index(symbols, motifs_encountered)]

        else:

            # The symbol possibilites are the motifs that are encountered in combination with the motifs that are not encountered

            remaining_motif_combinations = [set(i) for i in combinations(motifs_not_encountered, n_picks - len(motifs_encountered))]

            for i in remaining_motif_combinations:
                possibe_motifs = motifs_encountered.union(i)
                symbols = [set(i) for i in symbols]
                if possibe_motifs in symbols:
                    read_symbol_possibilities.append(get_symbol_index(symbols, motifs_encountered.union(i)))

        symbol_possibilities.append(read_symbol_possibilities)

    return symbol_possibilities

This will only work for the Coupon Collector Channel, will need to be changed for the Distracted CC case

[Parvfect]

Closing the Issue, going to make further changes in code optimization and generalization

Not sure why this line of code is where it is, seems to be done every time for no reason:

symbols = [set(i) for i in symbols]

Otherwise looks correct
