make known sub-components available for parsing

[MoralCode]

if a data source is already partially formatted,like this:

"hours": {
	"friday": "700AM-400PM",
	"monday": "700AM-400PM",
	"sunday": "Closed",
	"tuesday": "700AM-400PM",
	"saturday": "730AM-400PM",
	"thursday": "700AM-400PM",
	"wednesday": "700AM-600PM"
},

then it would be nice to be able to just parse the time range.

this should be straighforward as tweaking the internal API so its consistent with the public one and making a new release.

just leaving it here as a TODO

• Times
• Time (?)
• Days
• Day

[MoralCode]

can probably get away with not revealing the Time and Day classes cuz those are probably already handled by existing date and time parsers
