`MeshIO` classes Write methods fail/timeout and round-trip test fail

### Description

Some of the `MeshIO` (`Modules/IO/Mesh*`) classes `Write*` methods fail/timeout or the round-trip (write data, read back and compare the read values to the expected ones) fail.

### Steps to Reproduce

The failing tests are located in the `test` module of each `Modules/IO/Mesh*` module. The failing calls have been commented out in the tests and a `FIXME` tag was put in the comments while adding the tests for these classes in #3403.

### Expected behavior

Write methods work; tests do not timeout; round-trip checks pass.

### Actual behavior

Some of the write methods do not work; tests timeout (`MeshBYU`); round-trip checks do not pass.

### Reproducibility

%100.

### Versions

`master`.

### Environment

Issues were being reported in all platforms used by the CI builds. However, tests were passing on a Windows 7, MSVC 2019 machine.

Slightly related to this is the need to improve the buffer allocation method/buffer deletion, as noted in the referenced comment.
