[BUG] Typo in Watson SO parameters

[lconaboy]

In hmf/mass_function/fitting_functions.py the Watson fitting function has a typo for the high-z parameters, specifically in _defaults:

"alpha_hi": 0.874,
"beta_hi": 3.810,

should be

"alpha_hi":  3.810,
"beta_hi": 0.874,

i.e. alpha_hi and beta_hi should be swapped. This typo was in the original version on the arxiv (https://arxiv.org/pdf/1212.0095v1.pdf), but corrected later on (https://arxiv.org/pdf/1212.0095.pdf).

Thanks @Iconaboy -- this is being addressed in #142, and will be released in v3.4.2 soon.
