Unsized numbers without base solution

[YSJL]

I had the same problem as issue #116
However, I was able to fix the problem by adding a new type of number with the provided structure.
Already made a comment on said issue, but making a new one for visibility.

You can edit lexer.py, parser.py, ast.py using already existing structures.
For lexer,py:

• Add at line 89 within tokens = keywords + operators + ()
'UNSIZEDNUMBER',
• line 184
  unsized_number = '\'[0-1xXzZ?]'
• line 218
  @TOKEN(unsized_number)
def t_UNSIZEDNUMBER(self, t):
return t

For parser.py:

• line 1266
  def p_const_expression_unsizednum(self, p):
'const_expression : unsizednumber'
p[0] = UnsizedConst(p[1], lineno=p.lineno(1))
p.set_lineno(0, p.lineno(1))
• line 1281
  def p_unsizednumber(self, p):
'unsizednumber : UNSIZEDNUMBER'
p[0] = p[1]
p.set_lineno(0, p.lineno(1))
• line 1498
  def p_delays_unsizednumber(self, p):
'delays : DELAY unsizednumber'
p[0] = DelayStatement(UnsizedConst(
p[2], lineno=p.lineno(1)), lineno=p.lineno(1))
p.set_lineno(0, p.lineno(1))

For ast.py:

• line 267
  class UnsizedConst(Constant):
pass
