Numbers in parameters not converted back to their symbolic representation

[cosenal]

Pre-Report Checklist

• I am running the latest versions of pyQuil and the Forest SDK
• I checked to make sure that this bug has not already been reported
  NOTE: I am not sure if the underlying issue is the same as Pyquil converts real gate parameter to complex. #1701 1701

Issue Description

With the new parser (introduced in v4), parameters are no longer converted to symbolic number, e.g., $\pi/2$ is left as 1.5707963267948966 and not parsed back to pi/2.

The old behaviour was convenient, because it would make conversion from other languages (e.g. Cirq) to a Pyquil program and viceversa idempotent (related to Cirq#6714)

How to Reproduce

Code Snippet

from pyquil import Program
Program("RX(1.5707963267948966) 0").out()

Error Output

Until pyquil v3, the output used to be

'RX(pi/2) 0\n'

The parser had this feature of figuring out the representation of pi from a truncated decimal approximation.

Starting from pyquil v4, the number stays as

'RX(1.5707963267948966) 0\n'

Perhaps more accurate, but less convenient for the conversions I mentioned above.
