Add initial code for exercise 10
Rename random_fib() to gen_fib() and extract gen_pascal()

The sequences are not random (only the octave is chosen randomly)
and Pascal's triangles is in use too, not just a Fibonacci sequence
as the name of the function suggests.
Print number of notes generated in each sequence, for information
Add data for the first 10,000 terms of sequence A001223 from OEIS

First 10,000 terms of the sequence of differences between consecutive primes,
by N. J. A. Sloane.

https://oeis.org/A001223/b001223.txt

I then removed empty lines from the end of the file.
Add script to convert a sequence of integers to a Python array

I will use this script to prepare data for the Sequence of differences
between consecutive prime numbers for use in exercise 10.

Run:
cd data
./sequence-to-array.sh b001223.txt 10 1000

To output an array with the first 1000 values, on 100 lines of 10 values.
Add missing end of line after the array
Remove trailing spaces before newline in generated array
Complete exercise 10

I generated a sequence of notes using the 1,000 first differences
between prime numbers.

I also added in this commit the MIDI files generated in the same run
for the Fibonacci sequence and the Pascal's triangles sequence.
