[BUG] Order of precedence not honored in APPLY functions with exponents

[joeywhelan]

Mathematical order of precedence is not being followed for APPLY equations with exponentiation. Parentheses are necessary to ensure exponentiation has higher precedence. Redis Search version = 2.8.12

Examples:

• Incorrect

> FT.AGGREGATE txns * APPLY '(2*3^2)' AS Value LIMIT 0 1
1) "1"
2) 1) "Value"
   2) "36"

• Correct

> FT.AGGREGATE txns * APPLY '(2*(3^2))' AS Value LIMIT 0 1
1) "1"
2) 1) "Value"
   2) "18"
