Disable loupe's `customInspect` option to avoid collisions.

[OldStarchy]

One of my objects has a .inspect function that collides with chai/loupe's customInspect setting.

The options provided to loupe's inspect are hardcoded (which is why I'm opening the issue here rather than in loupe):

chai/lib/chai/utils/inspect.js

Lines 24 to 29 in 0b0353c

	let options = {
	colors: colors,
	depth: typeof depth === 'undefined' ? 2 : depth,
	showHidden: showHidden,
	truncate: config.truncateThreshold ? config.truncateThreshold : Infinity
	};

Setting customInspect: false below would disable the check.

There's already an issue over there questioning the validity of using a string-keyd 'inspect' function given that there is support for Symbols widely available chaijs/loupe#74, but it seems to have been missed by the maintainers of the repo.

Let's resolve this in chaijs/loupe#74. PRs welcome for that issue.
