Parquet Record Tests Fail on Rust 1.58

[tustvold]

Describe the bug

Initially noticed on #1174 but it would appear the formatting changes in Rust 1.58 have altered the formatting of floating point numbers causing the tests to fail

To Reproduce

Run the test_convert_double_to_string test on master, and it will fail with

Left:  1e-15
Right: 0.000000000000001
<Click to see difference>

thread 'record::api::tests::test_convert_double_to_string' panicked at 'assertion failed: `(left == right)`
  left: `"1e-15"`,
 right: `"0.000000000000001"`', parquet/src/record/api.rs:1096:9
stack backtrace:

Expected behavior

Test should not fail
