Remap ZFA's 'inferior raphe nucleus'.

ZFA's 'inferior raphe nucleus' (ZFA:0000366) is mapped to Uberon's
'dorsal raphe nucleus' (UBERON:0002043).

This is likely wrong for at least two reasons:

* the ZFA term refers to a nucleus that is part of the hindbrain,
  whereas the Uberon term refers to a nucleus that is part of the
  midbrain;
* according to Beecher, Beamer & Bartlett 2019 [1], the 'dorsal raphe
  nucleus' is one of the *superior* raphe nuclei, which makes it
  doubtful, even considering possible terminological differences across
  species, that it should be mapped to an *inferior* raphe nucleus.

The same reference states that the 'inferior raphe nucleus' is a complex
comprising the following nuclei:

* the 'nucleus raphe obscurus' (UBERON:0002684),
* the 'nucleus raphe pallidus' (UBERON:0002157),
* and the 'nucleus raphe magnus' (UBERON:0002156).

In Uberon, those three nuclei are the parts that make up the 'medullary
raphe nuclear complex' (UBERON:0002692), leading me to believe that this
complex is in fact what ZFA (along with Beecher, Beamer, & Bartlett)
calls the 'inferior raphe nucleus'.

So here, we remap ZFA's 'inferior raphe nucleus' to 'medullary raphe
nuclear complex', and also add a 'inferior raphe nuclei' synonym to the
Uberon term.
