Describe the bug
JSqlParser v3.0 doesn't support some foreign key reference option, include RESTRICT, SET NULL, SET DEFAULT.

Reference:

[CONSTRAINT [symbol]] FOREIGN KEY
[index_name] (col_name, ...)
REFERENCES tbl_name (col_name,...)
[ON DELETE reference_option]
[ON UPDATE reference_option]

reference_option:
RESTRICT | CASCADE | SET NULL | NO ACTION | SET DEFAULT

To Reproduce
When use JSqlParser parse below creation table SQL for table: foreign_key_reference_option_sample, there was exception:

create table foreign_key_reference_option_sample
(
id int primary key,
country_id int not null,
state_id int not null,
city_id int null,
person_id int not null,
career_id int not null,
key countryKey(country_id),
key stateKey(state_id),
key cityKey(city_id),
key personKey(person_id),
key careerKey(career_id),
CONSTRAINT fk_a FOREIGN KEY (country_id) REFERENCES t1 (country) ON UPDATE RESTRICT,
CONSTRAINT fk_b FOREIGN KEY (state_id) REFERENCES t1 (state) ON UPDATE CASCADE,
CONSTRAINT fk_c FOREIGN KEY (city_id) REFERENCES t1 (city) ON UPDATE SET NULL,
CONSTRAINT fk_d FOREIGN KEY (person_id) REFERENCES t1 (person) ON UPDATE NO ACTION,
CONSTRAINT fk_e FOREIGN KEY (country_id) REFERENCES t1 (country) ON DELETE RESTRICT,
CONSTRAINT fk_f FOREIGN KEY (state_id) REFERENCES t1 (state) ON DELETE CASCADE,
CONSTRAINT fk_g FOREIGN KEY (city_id) REFERENCES t1 (city) ON DELETE SET NULL,
CONSTRAINT fk_h FOREIGN KEY (person_id) REFERENCES t1 (person) ON DELETE NO ACTION
);

create table t1 (
id int primary key,
city int null,
country int not null,
state int not null,
person int not null,
career int not null,
key cityindex (city),
key countryindex (country),
key stateindex (state),
key personindex (person),
key careerindex (career)
);

Expected behavior
JSqlParser need to parse the table# foreign_key_reference_option_sample creation SQL successfully.
