Eventregistry

**Added**
- added `keywordSearchMode` parameter that can be used in `QueryArticles`, `QueryArticlesIter`, `QueryEvents`, `QueryEventsIter` and `QueryEvent` constructors.
- added `keywordSearchMode` parameter to the advanced query language


**Updated**
- types of parameters in the method calls
- updated several code example files

**Added**
- added use of the typing module. All parameters in the method calls use typing support to make it easier to understand what type is expected.
- added autosuggest methods `suggestEventTypes`, `suggestIndustries`, `getSdgUris`, `getSasbUris` - all to be used only when querying mentions
-

**Updated**
- `QueryArticles` class. Added filters `authorsFilter`, `videosFilter`, `linksFilter`
- `QueryMentions` class. Added several filters: `industryUri`, `sdgUri`, `sasbUri`, `esgUri`, `minSentenceIndex`, `maxSentenceIndex`, `showDuplicates`
- updated several code example files

**Updated**
- changed the logger. No longer printing out to console information about the host, etc
- removed two parameters from `EventRegistry` constructor:
- `logging` - if you wish to log requests to file, please call now `EventRegistry.setLogging(True)`
- `printHostInfo` - if you wish to see the host info, call `logging.getLogger("eventregistry").setLevel(logging.DEBUG)`
- `checkVersion()` is no longer automatically called in `EventRegistry` constructor. If you wish to see if there is an updated version of the module, please call the method manually.

**Updated**
- the `QueryEventArticlesIter` class will be significantly faster in returning the articles when you specify the language filter

**Added**

- added file `QueryMentions` that can be used to query mentions of specific event types. The class is currently in beta and not available to users unless they have permissions to use this endpoint. The classes `QueryMentions` and `QueryMentionsIter` can be used in the same way as classes for querying articles and events, except that some query parameters are addded and some removed. Examples for the classes were also added.

**Updated**
- When using method `initWithComplexQuery` we now check if the provided json is valid json object and report error in case it is not
- some bugs that appeared in edge cases when querying Event Registry using `EventRegistry` class have been fixed.

**Added**

- added `required` and `excluded` optional parameters to the TopicPage class to methods `addConcept`, `addKeyword`, `addCategory`, `addSource`, `addSourceLocation` and `addSourceGroup`.
- exceptions are now raised by the SDK library in case of status codes 204, 400, 401 and 403. Previously, the requests were repeated if status code was not 200. In case of these status codes it however doesn't make sense to simply repeat the requests as the query will for sure return the same exception. The meaning of the above status codes is described on the [documentation page](https://eventregistry.org/documentation?tab=introduction).
