issue when `defrecord` field names have the same names as internal method names

[ikappaki]

Hi,

there appears to be an issue with defrecord when any of the field names have the same name as any of the deftype methods it implements, e.g. the :seq field in the below comes back as an bounded method

#basilisp.pprint.Person{:c 2 :seq <bound method Person.seq of Person(b=1, c=2, meta=3, _recmap={})> :b 1}

To reproduce

1. Open up a REPL and define a record with a seq field

basilisp.user=> (defrecord Person [seq b c])
<class 'basilisp.user.Person'>

2. Create an instance of the record, notice how the seq field is bound to a fn rather than the passed in value of 1, and the rest of the values are shifted

basilisp.user=> (Person. 1 2 3)
#basilisp.user.Person{:c 2 :b 1 :seq <bound method Person.seq of Person(b=1, c=2, meta=3, _recmap={})>}

This is arises due to the definition of Person as a type with a seq method, amongst other methods which result to the same issue, as evident in the below macroexpansion.

Any ideas how easy would be to fix this, if at all possible?

basilisp.user=> (pp/pprint (macroexpand-1 '(defrecord Person [seq b c])))

I think we should throw an error when building a defrecord with invalid field names.
