Missing Series type arg in .loc

[khusmann]

Describe the bug
Series.loc can accept a series of bools, but this is not reflected in the type signature.

This shows a type error in VSCode:

const dfd = require("danfojs-node")


let s = new dfd.Series([12, 34, 2.2, 2, 30, 30, 2.1, 7])
s.loc(s.gt(20)).print()

Error:

Argument of type 'Series' is not assignable to parameter of type '(string | number | boolean)[]'

Expected behavior
No type errors :)
