Update to .NET 9 and apply upstream patches

Adapt parsing Current Solar System name

After observation of Current Solar System name now wrapped in 'Link' object.

Improve readability in program code

Adapt dict entries of interest for new samples

Adapt to new samples including the new 'Photon UI' mode in the game client.

Speed up searching the root using parallelism

Search multiple memory regions in parallel to reduce the time spent in this stage.

Reduce runtime expenses for composing dictEntriesOfInterest

Reduce complexity in serializing to JSON

Use the new mainstream library to serialize to JSON.

Prepare release - support distinguish versions

Harden the memory reading implementation

Adapt to a sporadically observed problem in memory reading: On 2020-02-25 and 2020-03-04 observed issue caused the whole memory reading to fail with a `System.OverflowException` out of `ReadBytes`, in both cases called via `ReadActiveDictionaryEntriesFromDictionaryAddress`.
See the added image for an example of the error.

Improve the dictionary reading:
+ Avoiding invoking `ReadBytes` with an invalid argument
+ Avoid stalling the whole reading process when we happen to read garbage in a single dictionary.

For the report from 2020-03-04, see the discussion with McMahon on Discord.

Reduce memory usage

Integrate the newer version of memory reading with reduced memory usage: https://github.com/Arcitectus/Sanderling/commit/c2451143e459521a35c63a66480a3deca71845da
