Change all public types in namespace Cysharp.Text to internal (axuno#372

)

* Change all public types in namespace Cysharp.Text to internal

* Regression caused by axuno#368
* Stop namespace collision with Cysharp.Text nuget package
* Affects: class, struct, interface, delegate, enum
* using https://github.com/zzzprojects/findandreplace on command line, so we can automate this step:
"fnr.exe" --cl --dir "SmartFormat.ZString\repo\src\ZString" --fileMask "*.cs,*.tt" --includeSubDirectories --caseSensitive --useRegEx --find "public (?=.*(class |struct |enum |interface |delegate ))" --replace "internal "

* Add a unit test to get an alert when Cysharp.Text objects are public

* Bump version to v3.3.2

Bump version to v3.3.1 (axuno#371)

* Bump version to v3.3.1

Bump version to v3.3.0 (axuno#356)

Resolves axuno#345 (axuno#346)

* Resolves axuno#345

* PluralLocalizationFormatter does treat numeric string as valid argument
* Restore behavior of v3.1.0 and before (don't convert numeric string to decimal for arg values)
* Bump version to v3.2.2
* Update appveyor and github CI scripts

Fix: Auto-detection of PluralLocalizationFormatter does not throw for…

… values not convertible to decimal (axuno#330)

* Resolves axuno#329

Current behavior, introduced in v3.2.0:
When PluralLocalizationFormatter.CanAutoDetect == true, values not convertible to decimal will throw then trying to IConvertible.ToDecimal(...)

New behavior:
When PluralLocalizationFormatter.CanAutoDetect == true, for values not convertible to decimal, IFormatter.TryEvaluateFormat(...) will return false

* Make PluralLocalizationFormatter.TryGetDecimalValue static

Bump version to v3.2.0 (axuno#315)

Fix: Newtonsoft.Json prior to version 13.0.1 is vulnerable

Newtonsoft.Json prior to version 13.0.1 is vulnerable to Insecure Defaults due to improper handling of expressions with high nesting level that lead to StackOverFlow exception or high CPU and RAM usage. Exploiting this vulnerability results in Denial Of Service (DoS).
