tira-misu dba962ebb8 Enable flatbuffer to initialize Parser from bfbs (#4283) (#5077)
* Enable flatbuffer to initialize Parser from bfbs (#4283)

Now its possible to generate json data from bfbs data type and flatbuffers data
and visa versa.

* add deserialize functionality in parser from bfbs
* add small usage sample

* Fix build break

* Merge branch 'pr/1' into fix-issue4283

* Fix buildbreak

* Build monster_test.bfbs with --bfbs-builtins

Attribute flexbuffer has be included in bfbs. Only with this attribute test
will run. By initialization a parser by a bfbs the attribute has to be known
for this filed. monsterdata_test.golden has a flexbuffer field so parse would
fail.

* Fix generate_code.sh

* Revert automatic indent changes by IDE

* Auto detect size prefixed binary schema files

* Use identifier (bfbs) to detect schema files
