dante depends on company, and company backend make my ocaml slow

[idhowardgj94]

As title,

I try to use ocaml recently, and find out that lsp + company is extremly slow, almost unusable.

after dig in this issue couple days, I figure out that dante's company dependencies and customize company backend make
completion slow, and situation get worse on ocaml.

not pretty sure why, but I just disabled dante for now.
