Summary

This PR implements Phase 1 of the 5D OpenSimplex2F noise implementation as outlined in issue #25.

Changes Made:

1. struct Grad5 - Added with 5 double components (dx, dy, dz, dw, dv)
2. struct LatticePoint5D - Added with 5 integer coordinates (xsv, ysv, zsv, wsv, vsv) and 5 double offset values (dx, dy, dz, dw, dv)
3. new_LatticePoint5D function - Allocates memory and initializes all 5 integer and double fields with proper skew offset calculation using formula: ssv = (xsv + ysv + zsv + wsv + vsv) * -0.211324865405187
4. OpenSimplex2F_context structure - Added struct Grad5 *permGrad5 field
5. Memory allocation in OpenSimplex2F - Properly allocates permGrad5 in the OpenSimplex2F function
6. Memory deallocation in OpenSimplex2F_free - Properly frees permGrad5 in the OpenSimplex2F_free function
7. 5D gradient array - Added GRADIENTS_5D[PSIZE] static array
8. Gradient initialization - Implemented 5D gradient initialization in setup_gradients function
9. 5D noise function - Added OpenSimplex2F_noise5 function declaration in header

Verification:

• All data structures compile without errors
• Code compiles with -Wall -Wextra --pedantic -O3 flags
• Tests pass successfully
• Memory is properly allocated and freed

Notes:

• Follows the existing pattern from 2D, 3D, and 4D implementations
• Maintains consistency with existing code style
• No memory leaks detected
