Improve performance of TimeEfficientLongestCommonSubsequenceCalculator

[staabm]

after #118 I measured the same workload with TimeEfficientLongestCommonSubsequenceCalculator.

turns out it also bottlenecks on max():

before this PR TimeEfficientLongestCommonSubsequenceCalculator is even slower then MemoryEfficientLongestCommonSubsequenceCalculator in this workload.

using the same approach we can see solid performance improvement with this PR and TimeEfficientLongestCommonSubsequenceCalculator is similar fast as MemoryEfficientLongestCommonSubsequenceCalculator but using way more memory:
