Description

Please include a summary of the changes being made within your PR. Please also include relevant motivation and context.
Updated to calculate the percentage of GC basecalls within the reads. In summary, a for loop is used to pull just the read lines from the fastq file and produce two new variables that represent either a total number of bases and a concatenated string of bases. These new variables were then used to count the occurrence of G and C present in the concatenated string and calculate the percentage of the reads that are G or C using the total number of bases variable. The output adds a line indicating the file read and the percentage of GC calculated. Additionally, the test.yml file has been updated to check for the updated output as opposed to the output of the original python script.
