Fix the build system to allow for C++14 or 17 support about indexed_bzip2 HOT 1 CLOSED

Manylinux host systems:

• manylinux1 is based on CentOS 5, which is EOL 2017-05-31
• manylinux2010 is based on CentOS 6, which is EOL 2020-10-30
• manylinux2014 is based on CentOS 7, which is EOL 2024-06-30

Manylinux pip requirements:

• manylinux1 requires pip >= 8.1.0
• manylinux2010 requires pip >= 19.0
• manylinux2014 requires pip >= 19.3
• manylinux_x_y requires pip >= 20.3

Pip Python requirements:

• Python 3.6 come with pip 18 and is EOL 2021-12-23

• 3.5 was EOL 2020-09-13
• 3.6 is EOL 2021-12-23
• 3.7 is EOL 2023-06-27
• 3.8 is EOL 2024-10-14
• 3.9 is EOL 2025-10-25

Use 'yum list installed | grep gcc' in the manylinux containers:

• CentOS 5 comes with GCC 4.8.2 and was EOL 2017-03-31
• CentOS 6 comes with GCC 8.3.1 and was EOL 2020-11-30
• CentOS 7 comes with GCC 9.3.1 and is EOL 2024-06-30

C++17 for indexed_bzip2 requires GCC >= 8.3.0

Therefore! Because of Python 3.6 and the insufficient pip version coming with it, manylinux1 theoretically has to be supported until 2021-12-23 even though the manylinux1 container is already EOL for 4 years! But, when it is not available, it will build from source and the oldest CentOS, 7, comes with gcc 9.3.1., which already fully supports C++17, so it should not be an issue. Unlike indexed_gzip or indexed_zstd, I'm also not using any external libraries eliminating another problem source.
