Cache align base addresses and fix address offsets

[radelja]

This pull request addresses #25 by cache aligning the base addresses of the source and target addresses, and #26 by adding 'patternIdx' to correctly determine the address offsets in the kernels.

• Adds new cache_line_size parameter to the Spatter generator to align start_source and start_target
• Adds new align_start_addresses parameter to enable or disable cache line alignment of start addresses
• Updates Gather, Scatter, MultiGather, and MultiScatter kernels to generate the correct address offsets
• Closes Target address not cache line aligned #25
• Closes Incorrect address offsets #26

@radelja - we wanted to note here that if the user doesn't want aligned addresses they may need to set this value to 1.

I have added a new align_start_addresses argument instead of requiring cache_line_size to be set to 1 to not align the addresses.

Pull Request Overview

This pull request addresses two issues related to memory address handling in the Spatter generator: cache aligning base addresses and fixing address offset calculations. The changes ensure proper cache line alignment for performance and correct address computation in memory access patterns.

• Adds cache line alignment functionality to the base source and target addresses
• Fixes address offset calculations in memory access kernels by incorporating patternIdx
• Updates parameter handling to support 64-bit addresses and alignment configuration
