Breaking API changes:

• In DebugProtocol fields which were @NonNull Long are now int as they
  are required. This brings the DAP implementation in LSP4J in line with
  the LSP implementation under the same conditions.

• In DebugProtocol fields which were @NonNull Boolean are now boolean
  as they are required. This brings the DAP implementation in LSP4J in
  line with the LSP implementation under the same conditions.

• In DebugProtocol fields which used to be defined as Long are now Integer.
  This is due to changes in DAP 1.36 and clarification sought from
  microsoft/debug-adapter-protocol#90

• The DebugProtocol's EvaluateResponse's field memoryReference was previously incorrectly
  declared as Long, it is now correctly declared as String

• CodeActionKindCapabilities.valueSet marked with @NonNull

• Parameters for the following requests have been changed from TextDocumentPositionParams

  • textDocument/signatureHelp changed to SignatureHelpParams
  • textDocument/hover changed to HoverParams
  • textDocument/declaration changed to DeclarationParams
  • textDocument/definition changed to DefinitionParams
  • textDocument/typeDefinition changed to TypeDefinitionParams
  • textDocument/implementation changed to ImplementationParams
  • textDocument/documentHighlight changed to DocumentHighlightParams
  • textDocument/prepareRename changed to PrepareRenameParams

• The LSP's Protocol Diagnostic field code was previouslyt incorrectly declared as String,
  it is now correctly declared as Either<String, Number>
