What does this pull request do?

• Implements the BCNM Amphibian Assault with captures from retail
• Uses Winters new PR that allows you to pass a target in onMobSpellChoose to write a smart WHM lua. All credits to @Xaver-DaRed for reviewing and improving my draft significantly.

WHM Logic findings

• Will cast various -na spells on allies if needed but not Stona (Maybe WHMs in newer content might)
• Will not Silena non-caster jobs
• Will heal when self or a nearby ally is 33% HP or below, only uses its strongest Cure or Curaga
• Will buff itself or allies quite often with haste, protect & shell
• Does seem to check which enfeebles are present and does not overlap them
• Does seem to check if Aquaveil is missing and only casts it if needed Sahagin_Study.zip
