Jack Franklin 8b9aa2fca6 Prefer eslint-mocha for linting .only in tests
DISABLE_THIRD_PARTY_CHECK=new npm module causes package-lock change

We can get rid of a custom script and use ESLint for these rules.

Additionally this means editors will highlight the issue in the editor.

/**
* Given a spec object recursively mapping properties to functions, creates a
* function producing an object of the same structure, by mapping each property
* to the result of calling its associated function with the supplied arguments.
*
* @func
* @memberOf R
* @since v0.20.0
* @category Function
* @sig {k: ((a, b, ..., m) -> v)} -> ((a, b, ..., m) -> {k: v})
* @param {Object} spec an object recursively mapping properties to functions for
* producing the values for these properties.
* @return {Function} A function that returns an object of the same structure
* as `spec', with each property set to the value returned by calling its
* associated function with the supplied arguments.
* @see R.converge, R.juxt
* @example
*
* const getMetrics = R.applySpec({
* sum: R.add,
* nested: { mul: R.multiply }
* });
* getMetrics(2, 4); // => { sum: 6, nested: { mul: 8 } }
