check value calculations for species marketed as parts

[sgaichas]

I think we drop all parts in get_comland_raw_data:

comlandr/R/get_comland_raw_data.R

Lines 96 to 105 in 10ecdd9

	# Remove fish parts so live weight is not double counted
	if(removeParts){
	comland.yr <- comland.yr[!NESPP4 %in% c('0119', '0123', '0125', '0127',
	'0812', '0819', '0828', '0829',
	'1731', '2351', '2690', '2699',
	'3472', paste0(348:359, 8),
	'3868', paste0(469:471, 4),
	paste0(480:499, 8), '5018',
	'5039', '5261', '5265'), ]
	}

This is to ensure species live weight isn't double counted.

Potential problem that needs checking:
Species like monkfish and skates often get different prices for parts.

Ensure that our code is getting the value correct for these species for our revenue calculations and indicators.

Not sure i understand exactly what is getting removed and why. Also not sure i understand where the double counting is coming in. For example a pull of ALL dogfish and skate codes results in the following plots.

Now after filteing this data pull to show just the codes that would have been removed we see this:

So it seems like there A LOT of other codes relating to species parts that are NOT removed. Not sure why.
