Fix import, typo, and redundant parentheses

[Pricstas]

1. Added import "fmt" to avoid missing dependencies.

2. Fixed a typo in a comment:

   • // take into consideration the possility that application reduced
   • // take into consideration the possibility that application reduced

3. Removed unnecessary parentheses in if condition:

   • if (pt != nil) {
   • if pt != nil {

Hi @supranational/blst-maintainers!

Just a friendly reminder about PR #252: it adds the missing fmt import, fixes a typo in the comment, and removes redundant parentheses:

• Added import "fmt" to avoid missing dependencies
• Corrected “possility” → “possibility” in a comment
• Simplified if (pt != nil) → if pt != nil
