Martchus 7bed9cd38c Remove TODOs about parsing/printing custom formats 
It makes likely more sense to implement that entirely in user code. The
parsing/printing functions for common formats have also been improved so
this is likely not very relevant anymore anyways.

Martchus 5acf422f71 Add useful operators to `DateTimeExpression` 
* Add serialization back to string, useful for implementing
  `TagValue::toString()`
* Add equality comparition

Martchus f20d596785 Add `DateTimeExpression` to keep track of parsed timestamp parts 
The existing timestamp parsers already internally keep track what parts
have been parsed via an index variable. This change exposes this
information as it can sometimes be useful to know what parts were actually
present in the timestamp.

Martchus a116c9e790 Avoid possibility of overflow in DateTime parsing functions 
* This is strictly undefined behavior so let's avoid it
* As a side-effect it is now possible to omit the separators in
  DateTime::fromIsoString()

Martchus 32780ed6a6 Support formatting ISO timestamps via DateTime::toString() with option to omit defaults 
Omitting components are also allowed when parsing ISO timestamps so it makes sense to
have something similar in the other direction as well.

Note that the idea comes from ID3v2.4.0 which stores timestamps in a subset of ISO 8601
similarily to what this library supports and it allows to omit default components as
well.

Martchus c834f8923d Allow omitting month and day when parsing ISO date 
This leaves only the year as mandatory component (other components
can already be omitted).

Martchus 357ede4ee7 chrono utils: Improve handling micro- and nanoseconds 
DateTime and TimeSpan have an accuracy of 100 nanoseconds.

This commit ensures this is also handled in toString() and
fromString() methods and adds relevant convenience methods.
