bug: html formats cancelled out with media column

https://github.com/abrignoni/iLEAPP/blob/92e095f60eec073203f16b1586ddf5825a59b0d1/scripts/ilapfuncs.py#L339-L354C49

theres a bug where if you include a media column as part of a data set, it will wipe out any html injected formatting.

line 341 splits the data set tuples into plain and html. then we check for media types on line 352. if so, then line 354 splits a new data set pair but it uses the `data_list` object from a few lines up that has been replaced with plain text during the earlier split.

my suggestion is we do this media detection inside the html output if block. the html output has some limitations and restrictions and needs some of this formatting and prep work to display things well. then inside the html output if block, we can use just the html data set since we fill that value above regardless of injected html tags or not.

lava does not need the style information so we can ignore that from the media column header. lava has its own style rules to apply.
